実験手順

2-(2,4-Dichlorophenyl)-2-(1H-1,2,4-triazol-1-ylmethyl)oxirane methanesulphonate salt (0.336 g, 1 mmole), 4-chlorobenzyl mercaptan, (0.159 g, 1 mmole) and anhydrous potassium carbonate (0.414 g, 3 mmole) were stirred in dry N,N-dimethylformamide (15 ml) at 70° C. for 72 hours. The reaction mixture was diluted with water (70 ml) and extracted with ethyl acetate (2×70 ml). The extracts were combined and evaporated to give an oil which crystallized on standing. Recrystallization from a mixture of ethyl acetate and n-hexane gave the title compound (0.23 g, 53%) m.p. 106°-107° C.
