Reaction Steps
4.35 g of 2-hydroxy-4-phenyl-2-trifluoromethyl-valeric acid ethyl ester is dissolved in 100 ml of diethyl ether and stirred at 0° C. with 1.3 g of lithium aluminum hydride for one hour at 0° C. and for 16 hours at room temperature. A little water is added while being cooled, and it is stirred for one hour. The diethyl ether phase is separated, dried (Na2SO4) and concentrated by evaporation and distilled on a bulb tube. 4.1 g of 4-phenyl-2-trifluoromethyl-1,2-pentanediol, boiling point 120° C./0.04 hPa, is obtained.
