Reaction Steps
An isopropyl magnesium bromide ether solution prepared by using 5.6 g of 2-bromopropane, 0.94 g of magnesium and 30 ml of diethyl ether, was dropwise added to a mixture comprising 5.0 g of 3,4-dimethoxybenzaldehyde and 50 ml of diethyl ether, followed by a reaction for 15 hours under reflux. The reaction mixture was put into ice water, and dilute sulfuric acid was added, followed by stirring. Then, the mixture was extracted with methylene chloride, followed by washing with water. The organic layer was dried over anhydrous sodium sulfate and then concentrated under reduced pressure to obtain 6.3 g of oily 1-(3′,4′-dimethoxyphenyl)-2-methylpropanol.
