To a well-stirred solution of propiophenone (20.1 g, 0.15 mol) in dry diethyl ether (125 ml) kept under nitrogen at room temperature was added a solution of phenylmagnesium bromide (55 ml, 3 M in diethyl ether) in dry diethyl ether (25 ml). The reaction mixture was stirred for 1 h and a mixture of a saturated ammonium chloride solution (100 ml) and water (50 ml) was added. The phases were separated and the aqueous phase was extracted with diethyl ether (100 ml). The combined organic phases was washed with a 0.5 N hydrochloric acid solution and dried over sodium sulphate. The solvent was evaporated in vacuo to give a solid residue which was trituated with cyclohexane (100 ml). The solid was collected by filtration and dried to give 26.4 g (83%) of 1,1-diphenyl-1-propanol.
