Participants

Reaction Steps

A mixture of potassium (Z)-methyl cyanocarbonimidodithioate (10.0 g, 58.7 mmol) and 2-chloroacetamide (6.04 g, 64.6 mmol) in ethanol (20 mL) was refluxed for 1 h. After cooling to ambient temperature, sodium methoxide (3.49 g, 64.6 mmol) was added to the mixture. The mixture was stirred at reflux for 3 hours. The mixture was cooled to ambient temperature and water (50 mL) was added. The precipitate formed was collected by filtration. The precipitate was further washed with water and dried in vacuo. The product was obtained as a yellow solid (3.372 g, 30%). 1H NMR (300 MHz, d6-DMSO) δ 6.96 (s, 2H), 6.89 (s, 2H), 2.64 (s, 3H); LC-MS: 190 (MH+).
