Versuchsvorschrift

To a solution of (S)-benzyl 1,1-diethoxypropan-2-ylcarbamate (844 mg, 3.00 mmol) in methanol (50 ml) was added 5% palladium on carbon (30 mg) and the mixture was stirred at room temperature for 2 hr under hydrogen atmosphere. The reaction mixture was filtered on Celite and washed with methanol (200 ml) and the filtrate was concentrated in vacuo to obtain the title compound (442 mg, 100%).
