実験手順

37 g (0.13 mol) of 4-bromo-1-(4-chlorophenyl)-2,2-dimethyl-3-butanone, 13.3 g (0.019 mol) of 1,2,4-triazole and 53.8 g (0.39 mol) of potassium carbonate are heated under reflux in 300 ml of acetone for 8 hours. The mixture is allowed to cool, the inorganic residue is filtered off with suction and the filtrate is concentrated. The residue is taken up in chloroform and the mixture is washed with water, dried over sodium sulphate and concentrated. The residue is stirred with diethyl ether, filtered off with suction and dried at 50° C. in vacuo. 18.8 g (52% of theory) of 1-(4-chlorophenyl)-2,2-dimethyl-4-(1,2,4-triazol-1-yl)-3-butanone of melting point 127° C. are obtained. ##STR18##
