Diethyl Ether → 1-(4-Biphenyl)-1-propanol

Participants

Reaction Steps

To a solution of 4-phenylbenzaldehyde (1.20 g) in diethyl ether (13.2 mL), ethylmagnesium bromide (about 3.0 mol/L, solution in diethyl ether, 3.29 mL) was added at 0° C. After stirring the mixture at room temperature for 3 hours, the precipitate was recovered by filtration. After dissolving the recovered precipitate in a liquid mixture of ethyl acetate and a saturated aqueous solution of ammonium chloride, three extractions were conducted with ethyl acetate. The combined organic layers were washed with saturated brine. After passage through a phase separator, the washed organic layers were concentrated under reduced pressure. The resulting residue was purified by silica gel column chromatography (n-hexane:ethyl acetate=100:0-70:30) to give 1-(biphenyl-4-yl)propan-1-ol as a colorless solid (1.27 g).
