Procedure

To a stirred mixture of 4-chloro-2-(methylthio)pyrimidine-5-carbonitrile (0.843 g, 4.54 mmol) and zinc dust (1.48 g, 22.71 mmol) in ethanol (7.5 mL) and water (1.4 mL) was slowly added acetic acid (0.29 mL, 5.13 mmol). The resulting reaction mixture was vigorously stirred for 3 h. The solids were removed by filtration and the filtrate concentrated in vacuo. The residue was chromatographed on silica gel 60 (35 g), eluting with 10:1-20:89-70 CH2Cl2:2-propanol:hexane to give the title compound. M.S. (M+1): 152.
