Procedure

Lithium aluminum hydride (100 mg) was added to a solution of isopropyl 2-chloro-4-isopropoxybenzoate (675 mg) in ether (6.8 ml) and the mixture was stirred for 2 hr. To the reaction mixture were dropwise added successively water (0.8 ml), a 1N aqueous sodium hydroxide solution (0.8 ml) and water (2.4 ml) under ice-cooing, and the mixture was stirred for 30 min at room temperature. Then ether and water were added and the organic layer was separated. The resulting product was extracted with ether from the aqueous layer. The organic layers were combined, washed with saturated brine, and dried over anhydrous magnesium sulfate. The solvent was evaporated to give the objective compound (513 mg) as a brown oil.
