To a solution of methyl mercaptan-DMF solution (methylmercaptan 66 g/DMF 306 g) (3.8 ml) and methyl 4-(2-chloro-5-nitrophenyl)-6-methyl-2-phenyl-5-pyrimidinecarboxylate (1.5 g) in tetrahydrofuran (25 ml) was added and the mixture was stirred for 3 hours at ambient temperature. The reaction mixture was evaporated in vacuo and the residue was dissolved in a mixture of water (50 ml) and ethyl acetate (100 ml). The organic layer was washed with a saturated aqueous solution of sodium chloride and dried over magnesium sulfate. The solvent was distilled off to give a residue, which was chromatographed on silicagel eluting with a mixture of n-hexane and ethyl acetate (10:1). The fractions containing the desired product were combined and concentrated in vacuo. The crystalline residue was recrystallized from n-hexane to afford methyl 6-methyl-4-(2-methylthio-5-nitrophenyl)-2-phenyl-5-pyrimidinecarboxylate (0.2 g).
