Procedure details

Under a nitrogen atmosphere, tetrahydrofuran (40 mL) was added to N-{3-[3-cyclopropyl-1-(2-fluoro-4-iodo-phenyl)-6,8-dimethyl-2,4,7-trioxo-1,2,3,4,7,8-hexahydro-pyrido[2,3-d]pyrimidin-5-ylamino]-phenyl}-acetamide (5 g) and a methanol solution (1.57 g) containing 28% sodium methoxide was added and the mixture was stirred at room temperature for 4 hours. Acetic acid (0.56 mL) was added to the mixture and the mixture was stirred at room temperature for 30 min. And then water (40 mL) was added and the mixture was further stirred for 1 hour. The crystals were collected by filtration and dried under reduced pressure at 40° C. to give trametinib (4.75 g). Its HPLC content of A impurity is 0.42 wt %.

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.
