Reaction Steps

4-Carboxybenzaldehyde (1.0 g, 6.66 mmol) was dissolved in anhydrous tetrahydrofuran (50 mL) and cooled to 0° C. To the mixture was added isobutylmagnesium chloride (16 mL, 32 mmol, 2.0 M solution in THF). The reaction mixture was warmed to room temperature and stirred for 2 hours. The solution was acidified with 50% sulfuric acid in water and the THF was removed under vacuum. The aqueous phase was extracted twice with dichloromethane. The combined organic layers were washed with brine, dried (MgSO4), filtered and evaporated to give the desired compound (950 mg) as grey powder.
