Reaction Steps

Diborane (192 ml of a 1.0 M solution in THF) was added dropwise over 25 minutes to a solution of 2-methyl-3-(4-bromophenyl)propanoic acid (38.9 g) in THF (240 ml) at 0° C. The reaction mixture was stirred for 45 minutes at 0° C. and then allowed to warm to ambient temperature over 2 hours. Water (120 ml) was added followed by solid potassium carbonate (144 g) and then more water (80 ml). The reaction mixture was extracted with diethyl ether (3×250 ml), the combined organic layers were dried (MgSO4) and the solvent was evaporated to give 2-methyl-3-(4-bromophenyl)propanol as a yellow oil (37.4 g), mass spectrum (+ve CI): 248 (M+NH4)+.
