Sulfuric Acid → Benzenepropanol, 3-(trifluoromethyl)-

Participants

Reaction Steps

A solution of 57 g of oxirane in 120 ml of diethyl ether is added dropwise (at 0° to 10° C.) to a Grignard solution prepared from 14.8 g of magnesium and 100 g of 3-(chloromethyl)benzotrifluoride in 450 ml of diethyl ether. The mixture is subsequently stirred at room temperature for 1 hour, and 300 ml of 10% strength sulfuric acid are then added, while cooling with ice. The organic phase is collected and extracted twice more with diethyl ether, and the combined organic phases are dried over magnesium sulfate and distilled. 76.7 g of 3-(3-trifluoromethylphenyl)propan-1-ol (b.p. 85° to 95° C. under 0.02 mm Hg) are thus obtained.
