Synthesis routes and methods I
Procedure details
The reaction was carried out in a reaction mixture (30 ml), comprising 500 mM 3-cyanopyridine, 40 mM potassium phosphate buffer (pH 7.0) and resting cells (dry weight 2.3 mg). During the reaction, 3-cyanopyridine (500 mM) was added 7 times as soon as it was consumed. In this manner, 4.0 M 3-cyanopyridine was added in the course of 15 h and 3.89 M (475 g/l) nicotinamide was formed, corresponding to a yield of 97.3%. Nicotinic acid was not formed.

Procedure details
High performance liquid chromatography was used to detect Nampt reaction products. HPLC was performed with Waters 515 pumps and a 2487 detector (Waters, Mass.) with a Supelco LC-18-T column (15 cm×4.6 cm; Supelco, Pa.). The Nampt reaction was conducted at 37° C. for 15 min in 500 μl of reaction buffer (50 mM Tris-HCl [pH 7.5], 10 mM MgCl2, 50 mM nicotinamide, 0.2 mM PRPP) with 50 μg of the recombinant Nampt protein. The reaction was terminated by adding 125 μl of 1 M HClO4. Protein was then precipitated at 18,000 g, and 500 μl of the supernatant was neutralized with 40 μl of 3 M K2CO3. After centrifugation, 100 μl of sample was mixed with 400 μl of Buffer A (50 mM K2PO4/KHPO4, pH 7.0) and loaded into the HPLC system. The products from Nampt reaction were monitored by absorbance at 261 nm. Results of HPLC detection of Nampt reaction products showed that the mouse Nampt produced nicotinamide mononucleotide (NMN) from nicotinamide and PRPP (see, e.g., FIG. 4D). Nampt failed to catalyze the synthesis of nicotinic acid mononucleotide (NaMN) from nicotinic acid and PRPP (see, e.g., FIGS. 13A and 13B), confirming the substrate specificity of this enzyme. In isolated reactions, it was also confirmed that Nmnat catalyzed the synthesis of NAD from NMN and ATP.

Procedure details
0.096 mole of 3-cyanopyridine was dissolved in 5.556 mole of water and 0.0115 mole of MnO2, prepared by above method, was added to this. The mixture was refluxed at 105° C. for 8 hrs. The reaction mixture was cooled and filtered. The filtrate was evaporated in dryness to get solid nicotinamide 0.095 mole. Yield of isonicotinamide was 98.9 mole %.

Synthesis routes and methods IV
Procedure details
In this Example a USP grade nicotinamide product was recovered from a crude nicotinamide product medium. The crude contained 39.7% nicotinamide, 2.15% sodium nicotinate and 0.14% 3-cyanopyridine. These and all other percentages given in this Example are percentages by weight unless indicated otherwise. The total sodium content of the medium was 0.38%. On a dry basis, the reaction crude contained 93.7% nicotinamide, 5.07% sodium nicotinate, 0.33% 3-cyanopyridine, and 0.9% total sodium. Cation and weak base resins were utilized in the recovery process. The cation exchange resin was Dowex Marathon C, a sulfonated copolymer of styrene and divinylbenzene (gel form). The weak base resin was Dowex Marathon WBA, a dimethylamine-functionalized chloromethylated copolymer of styrene and divinylbenzene (macroporous form with a monodisperse size distribution). After washing with deionized water, these resins were loaded into columns each having an inner diameter of 15 mm and a height of 30 cm, leaving about 1.5 inches head space at the top of the columns. The reaction crude was then successively treated over the cation-exchange resin (at 28 ml/min), the weak base resin (20 ml/min), the cation-exchange resin (28 ml/min), and the weak base resin (20 ml/min). The cation-exchange resin was regenerated after every ten bed volumes of reaction crude, by a cycle that included a water wash (20 ml/min, 1.25 bed volumes), a 12% sulfuric acid strip (7 ml/min, 1 bed volume), and another water wash (20 ml/min, 1.25 bed volumes). The weak base resin was regenerated after every five bed volumes of reaction crude, by a cycle including a water wash (20 ml/min, 1.6 bed volumes), a 4% sodium hydroxide strip (20 ml/min, 1 bed volume), and another water wash (2.6 bed volumes). The feeds were analyzed by HPLC after the first pass cation-exchange and weak base, and second pass cation-exchange and weak base. Typical results from such experiments are presented in Table 1 below, top. The lower section of Table 1 gives a typical product analysis on a water free basis. The extreme right hand column of Table 1 sets out the results of an analysis of the product after recovery by evaporation (no crystallization performed). As can be seen, this processing reduced the 0.9% initial sodium to an undetectable level, and the initial 5.07% nicotinate to 0.13% (as nicotinic acid) on a dry weight basis, providing a USP grade nicotinamide.
