Reaction Steps

To a stirred, cooled (0° C.) solution of 0.70 g (0.0039 mol) of cis-3-(benzoylthio)propenoyl chloride in 40 ml of dichloromethane under nitrogen was added dropwise 0.21 ml (0.0039 mol) of propargylamine as a solution in 10 ml of dichloromethane. After 15 min, 0.43 ml (0.0039 mol) of triethylamine was added dropwise. The reaction was allowed to stir at 0° C. for 2 h, poured into 10% aqueous hydrochloric acid, and extracted three times with ethyl acetate. The combined organic layers were washed with water, brine, and dried over magnesium sulfate. Filtration and removal of solvents gave 0.49 g (65% yield) of N-(2-propynyl)-cis-3-(benzoylthio)acrylamide as a white powder, m.p. 131°-134° C., as described in Table 1.
