실험 절차

A solution of 2-amino-4-methylpyridine (1.08 g, 10 mmol) and benzoyl isothiocyanate (1.63 g, 10 mmol) in acetone ( 15 mL) was stirred at RT for 1.5 h. The precipitate formed was filtered and washed with acetone to afford 1 -benzoyl-3-[4-methylpyridin-2-yl]-thiourea as a solid. This material was stirred with 2 N NaOH solution (15 mL) at 110° C. for 1 h, then cooled to RT, and the precipitate formed was washed with water and dried to provide (4-methylpyridin-2-yl)-thiourea (0.90 g, 53%). MS m/z 168 (M+H)+.
