Participants

Reaction Steps

A mixture of 500 mg (1.52 mmol) of N-[2-(4-benzyl-2-chlorophenoxy)ethyl]-cyclopropane carboxyamide, 614 mg (1.52 mmol) of a Lawesson's reagent and 20 ml of anhydrous toluene was refluxed by heating with stirring. After 20 minutes, the reaction mixture was cooled and concentrated under reduced pressure. The residue was subjected to silica gel chromatography to give 487 mg of N-[2-(4-benzyl-2-chlorophenoxy)ethyl]-cyclopropane thiocarboxyamide as a colorless oily substance nD23.6 1.6041). After one week, the oily substance caked as a white solid (m.p. 90°-92° C.).
