실험 절차
A solution composed of 5.0 g of (E)-3-(2-chloro-5-nitrophenyl)-2-propenamide, 4.4 g of Lawesson's reagent and 100 ml of tetrahydrofuran was stirred under a positive argon atmosphere at room temperature for 16 hr. The volatiles were then removed in vacuo and the residual materials slurried with 100 ml of methylene chloride to yield (E)-3-(2-chloro-5-nitrophenyl)-2-propenethioamide as a orange solid; m.p. 236°-238° C. from acetonitrile.
