Participants

Reaction Steps

0.65 g (1.4 mmol) of methyl 3-{4-acetylamino-2-[3-(2-chloro-4,5-difluorobenzoyl)ureido]phenyl}acrylate was dissolved in 8 ml of tetrahydrofuran, and 8 ml of H2O and 0.17 g (7.2 mmol) of lithium hydroxide were added. After 15 hours at room temperature, the mixture was made acid with 2 N hydrochloric acid and extracted with ethyl acetate. The organic phase was dried, concentrated and stirred up with diethyl ether. The resulting precipitate was filtered off with suction and yielded 77 mg (13%) of the desired product.
