Reaction Steps

To a solution of ethyl 4-formyl-6-(methylthio)-2-phenylpyrimidine-5-carboxylate (600 mg, 1.98 mmol) in ethanol (15 mL) was added hydrazine dihydrochloride (0.2 g, 1.98 mmol) and the mixture refluxed for 1 hour. The precipitated solid was filtered and dried in vacuum. The desired product (520 mg) was obtained by column chromatography over silica gel using methanol/dichloromethane as eluent. 1H-NMR (400 Hz, DMSO-d6): δ 13.19 (s, 1H), 8.54 (d, J=8.0 Hz, 2H), 8.36 (s, 1H), 7.64-7.58 (m, 3H), 2.67 (s, 3H); MS m/z 271.1 (M+1).
