To a solution of 3-cyclopropylprop-2-yn-1-amine (4.61 g) in ethanol (50 mL) was added 4-thioxo-1,3-thiazolidin-2-one (3.24 g), and the mixture was stirred at room temperature for 2 hr. The reaction mixture was concentrated, and the residue was purified by silica gel column chromatography (NH, ethyl acetate/hexane) to give the title compound (4.20 g).
