Procedure details

To a suspension of urea (80 g, 1.333 mols) in acetic acid (100 ml), phosphoric acid (8 ml) was added, followed by iminostilbene (20 g, 0.103 mols), under stirring at 25-30° C. The resulting reaction mixture was worked up according to the method of Example 1 to produce carbamazepine, which was identical to the product of Example 1.

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.
