1H-1,2,4-Triazole → 3,3-Dimethyl-4-phenyl-1-(1H-1,2,4-triazol-1-yl)butan-2-one

Participants

Reaction Steps

74 g (0.29 mol) of 1-bromo-3,3-dimethyl-4-phenylbutan-2-one, 40 g (0.58 mol) of 1,2,4-triazole and 80 g of potassium carbonate are dissolved in 700 ml of acetone, and the solution is heated under reflux for 3 hours. Thereafter, it is allowed to cool and is filtered off under suction from the inorganic residue, and the filtrate is concentrated. The residue is recrystallized from ether. 34.1 g (48.4% of theory) of 3,3-dimethyl-4-phenyl-1-(1,2,4-triazol-1-yl)-butan-2-one of melting point 79° C. are obtained. ##STR25##
