Procedure

A solution of 2-methyl-2-thiopseudourea sulfate (6.9 g, 0.025 mol) in 30 ml of sodium hydroxide (4%) was added a solution of 4-methylbenzoyl chloride (3.4 g, 0.022 mol) in ether (10 ml) at room temperature. The reaction mixture was stirred overnight and the precipitated solid was filtered, washed with water, later hexanes and dried under high vacuum. N-(4-methylbenzoyl)-S-methylisothiourea: yield 4.60 g (quantitative); purity 98% (HPLC); 1H-NMR (CD3OD) δ 2.4 (s, 3H, CH3), 2.6 (s, 3H, SMe), 7.2 (d, 2H, ArH), 8.1 (d, 2H, ArH).
