Synthesis routes and methods I

Procedure details

A suspension of 10 g of iminostilbene in 100 ml toluene was treated with 20.2 g of sodium cyanate and 27.5 g of mandelic acid and was heated to reflux for about 10 hrs. The reaction mixture was cooled to room temperature and charged with sodium hydroxide solution and maintained for 8 hrs. The resulting suspension was filtered, washed with water and dried to give 11 g of carbamazepine.
