Reaction Steps

To a cold (−78° C.) solution of 1,4-dibromobenzene 1 (42.4 mmol, 10 g) in THF (60 mL) was added butyl lithium(42.4 mmol, 2.5 M in hexane). The mixture was stirred at −78° C. for 1 h. 2-methylpropenal (42.4 mmol, 2.97 g) was added. The mixture was stirred at −78° C. for 1 h. NH4Cl was added. The mixture was extracted with EtOAc. The organic extract was washed with brine, dried and concentrated to an oil. Chromatography (5-15% EtOAc/hexane) gave the desired alcohol.
