Procedure

To a solution of 4-(-Boc-L-valyloxy)butyric acid benzyl ester (1.2 g, 3 mmole) in ethyl acetate/methanol 5 ml/5 ml) was added palladium black (20 mg). The reaction mixture was kept under hydrogen at atmospheric pressure for 2 hr. The suspension was filtered through Celite and dried, giving the title product, 840 mg.
