Similarly, 0.7 g of (+)-[(E)-1-(2,4-dichlorophenyl)-2-(1,2,4-triazol-1-yl)-4,4-dimethyl-1-penten-3-yl]-(-)-menthoxyacetate was treated with 20 cc of a 90% aqueous ethanol solution containing 0.1 g of potassium hydroxide and the resulting crude crystals were recrystallized from a carbon tetrachloride-n-hexane mixture to obtain 0.3 g of (+)-(E)-1-(2,4-dichlorophenyl)-2-(1,2,4-triazol-1-yl)-4,4-dimethyl-1-penten-3-ol: [α]D24 +26.0 (c=1.0, CHCl3); melting point 160°-161° C.
