Reaction Steps

A 1.6M solution of n-butyllithium in hexane (4 ml) was added to a solution of 4-bromo-3-chloroanisole (CAS Reg. No. 50638-46-5, 1.3 g) in THF (20 ml) at −78° C. The mixture was stirred for 30 min at −78° C. Acetaldehyde (0.7 ml) was added to the mixture. The mixture was allowed to warm to room temperature. Water (50 ml) was added and extracted with DCM. The combined organic layers were dried over Na2SO4 and concentrated to an oil to give the title compound (983 mg) as colorless oil. MS (m/e)=186 [M+].
