실험 절차

A mixture of acetylthiourea (591 mg, 5 mmol) and 1,3-dichloroacetone (667 mg, 5.25 mmol) in acetone (15 mL) was heated at reflux for 7 hours, cooled to room temperature, diluted with ethyl acetate, washed with water and brine, dried (MgSO4), filtered and concentrated. The concentrate was purified by column chromatography to give the title compound. MS (DCI) m/e 191 (M+H)+; 1H NMR (300 MHz, DMSO-d6) 12.21 (s, 1H), 7.22 (s, 1H), 4.70 (s, 2H), 2.13 (s, 3H).
