Procedure

To a solution of 3-(tert-butyldimethylsilyloxy)dihydrofuran-2(3H)-one (11 g, 49 mmol) in methanol was added 7 N ammonia in methanol (20 mL, 140 mmol). The reaction was stirred in a sealed tube for 2 days. The solvent was removed in vacuo to yield (S)-2-(tert-butyldimethylsilyloxy)-4-hydroxybutanamide (4.85 g, 20.8 mmol) as a white solid. [M+H] calc'd for C10H23NO3Si, 234. found, 234.
