Reaction Steps

589 mg (3.0 mmol) of ethyl 1.2-benzoisoxazole-3-carboxylate in solution in 10 ml of tetrahydrofuran are added to a suspension of 129 mg (3.5 mmol) of lithium aluminum hydride in 5 ml of tetrahydrofuran. The reaction mixture is stirred for one hour at 60° C. and then treated by adding 2 ml of methanol dropwise, filtered through celite and rinsed with ethyl acetate. The organic phases are combined, dried over sodium sulfate and evaporated. The residue obtained is purified by chromatography on silica gel, elution being carried out with a 60/40 heptane/ethyl acetate mixture. 180 mg (39%) of benzoisoxazol-3-ylmethanol are obtained in the form of a white solid.
