Procedure details
A mixture of 3-(4-amino-1,3-dihydro-1-oxo-2H-isoindol-2-yl)-glutaric acid (5 g) and urea (1.08 g) in N,N-dimethylformamide (25 ml) was stirred and heated under reflux for 3˜4 hours. The reaction mixture concentrated under reduced pressure at 60° C. and then was added into ice water by being stirred rapidly. After filter, the cake was washed with isopropanol. The crude product was recrystallized from isopropanol and active carbon to give 1.4 g of off-white target compound. Yield: 30%. mp: 252.1˜254.3° C.

Open Reaction Database (ORD) |
|
Description
|
The Open Reaction Database (ORD) is an open-access schema and infrastructure for structuring and sharing organic reaction data, including a centralized data repository. The ORD schema supports conventional and emerging technologies, from benchtop reactions to automated high-throughput experiments and flow chemistry. Our vision is that a consistent data representation and infrastructure to support data sharing will enable downstream applications that will greatly improve the state of the art with respect to computer-aided synthesis planning, reaction prediction, and other predictive chemistry tasks. |
