Procedure

tert-Butyl [methyl(6-cyano-2-pyrimidinyl)amino]acetate (1.63 g, 6.56 mmol) and methyl thiosalicylate (3.31 g, 19.7 mmol) were dissolved in toluene (50 ml), and triethylamine (2.76 ml, 19.7 mmol) was added thereto. The mixture was refluxed for 18 hrs. The solvent was evaporated, and the residue was recrystallized from ethanol to give the titled compound (1.20 g, 39%) as pale yellow crystals.
