Reaction Steps

20.7 g (0.3 mole) of 1,2,4-triazole, 4.15 g (0.103 mole) of sodium hydroxide and 1 ml of water were added to a solution of 71.55 g (0.3 mole) of 2-tert.-butyl-2-(4-chloro-phenyl-ethyl)-oxirane in 125 ml of N-methyl-pyrrolidone at room temperature, with stirring. The reaction mixture was heated at 120° C. for 4 hours, with stirring, during which a dry stream of CO2 -free air was slowly passed through. Thereafter, the mixture was worked up by a procedure in which the solvent was distilled off under reduced pressure and the residue which remained was washed with water and then dried and stirred with 150 ml of benzine. The solid product which deposited was filtered off and dried again. 81.9 g (88.8% of theory) of 1-(4-chloro-phenyl)-4,4-dimethyl-3-(1,2,4-triazol-1-yl-methyl)-pentan-3-ol were obtained in this manner.
