Diethyl Ether → 1-(4-Bromophenyl)-1-cyclohexylethanol

Participants

Reaction Steps

A solution of (4-bromophenyl)(cyclohexyl)methanone (step 63.2) (3.1 g, 11.60 mmol) in THF (30 ml) was immersed in an ice-bath, followed by dropwise addition of MeMgBr (3M) in diethylether (7.74 ml, 23.21 mmol). The yellow reaction solution was stirred in the ice-bath for 1.5 hrs. The reaction mixture was quenched carefully with saturated aqueous NH4Cl solution and taken up in ethyl acetate. The organic phase was separated and washed with brine. The organic phase was dried over Na2SO4, filtered and concentrated in vacuo to obtain the title compound as yellow oil.
