Reaction Steps

To 2-(2,4-Dichlorophenyl)-2-(1H-1,2,4-triazol-1-ylmethyl)oxirane (6.7 g) in dimethylformamide (198 ml) at 60° C. was added dropwise over 25 minutes a solution of sodium cyanide (2.84 g) in water (49 ml). Heating at 60° C. was continued for five hours. The reaction mixture was then cooled, poured into water (900 ml), and extracted with ethyl acetate (3×150 ml). The combined organic extracts were washed with saturated aqueous brine, dried (Na2SO4 ) and evaporated to dryness to give a pale yellow solid (6.1 g) which was triturated with ethyl ether. The residual solid was recrystallized from ethyl ether/methanol to give the title compound, 4.13 g (56%), m.p. 217°-219° C.
