Reaction Conditions

Reaction Steps

To a solution of 2-bromo-5-ethoxy-4-methylbenzoate (660 mg, 2.23 mmol) in ether (20 mL) at 0° C. was added DIBAL (5.75 mL, 5.75 mmol, 1 M in toluene). The reaction was stirred at 0° C. for 10 minutes. EtOAc (20 mL) and wet silica gel (˜50 g silica gel and 3 mL of water) were added portion wise at 0° C. The resulting slurry was stirred for ˜15 minutes and was filtered, washed with EtOAc (20 mL). The organic phase was dried over sodium sulfate, filtered and concentrated. The residue was purified on a silica gel column eluting with EtOAc/hexanes (20/80) to give the title intermediate (550 mg) as colorless liquid.
