5-Bromo-4-methyl-thiazol-2-ylamine (1.35 g, 7 mmol,) was dissolved in methanol abs. (13.5mL) and sodium methanethiolate (0.6 g, 7.7 mmol) 1.1 equiv.) was added portionwise at rt. After stirring overnight, the dark colored mixture was concentrated under reduced pressure and purified over a 50 g silica cartridge (NH2-modified) with ethyl acetate as eluent. The desired fractions were evaporated to give the title compound as a light yellow solid: 180 mg, MS (ISP): m/e 161.1 (M+H)+
