Versuchsvorschrift
A solution of ethyl 2-(methylthio)-4-(phenylamino)pyrimidine-5-carboxylate (4.0 g, prepared according to the reported preparation in Barvian, M.; et al. J. Med. Chem. 2000, 43, 4606) in ethanol (50 mL) was treated with 2 N lithium hydroxide (50 mL) at room temperature for 16 hours. The reaction mixture was washed with ether and then brought to pH 6 via the addition of 1 N hydrochloric acid. The resulting precipitate was collected by filtration, azeotroped with toluene and dried under vacuum to obtain the title compound (2.2 g) having the following physical data.
