Procedure

Ethyl 4-(4-cyanophenyl)-6-methyl-2-thioxo-1-[3-(trifluoromethyl)phenyl]-1,2,3,4-tetrahydro-5-pyrimidinecarboxylate (Example 3; 1000 mg, 2.24 mmol), iodomethane (350.5 mg, 2.47 mmol) and potassium carbonate (341 mg, 1.82 mmol) are dissolved in 20 ml acetone. The reaction mixture is stirred at room temperature overnight and the solvent is removed in vacuo. The product is purified by column chromatography (silica gel; eluent: cyclohexane-ethyl acetate, gradient 90:10 to 50:50).
