実験手順

The II-B isomer (2.9 g, 0.01 mole; m.p. 78°-79° C.) of 1-(4-chlorophenyl)-4,4-dimethyl-2-(1,2,4-triazole-1-yl)-1-pentene-3-one (Compound No. 1') was dissolved in methanol (50 ml). The isomer was allowed to react with sodium borohydride and then treated in the same manner as in Example 1. The residue obtained was recrystallized from a 1:10 mixture of carbon tetrachloride and n-hexane to obtain 2.2 g (yield 76%) of the I'-B isomer (m.p. 116°-117° C.) of Compound No. 1. The elementary analysis and NMR spectrum of the compound are shown below.
