Participants

Reaction Conditions

Reaction Steps

A solution of 4 g (16.5 mmol) of ethyl 4-bromophenylacetate in 60 ml of diethyl ether was treated with 26 ml (36.4 mmol) of a 1.4M solution of methylmagnesium bromide in toluene/tetrahydrofuran (3:1) and the mixture heated at 40° C. for 1 hour and then cooled. 100 ml of saturated aqueous ammonium chloride were added and the phases separated. The organic phase was dried over magnesium sulfate, filtered and evaporated to give 3.5 g (93%) of 1-(4-bromophenyl)-2-methyl-propan-2-ol as a colorless oil. [Mass spectrum (ESI) MH+ =229].
