실험 절차
(2R,4S)-1-(tert-Butyloxycarbonyl)-2-(4,4'-Dimethoxytrityl)oxymethyl-4-azido-pyrrolidine 40 (2.72 g, 5 mmol) in methanol (75 ml) was hydrogenated in the presence of 10% palladium on charcoal (0.3 g) at room temperature and 5 atm pressure. After 12 h, the catalyst was filtered, washed with methanol (20 ml) and the solvent removed under vacuum. Yield 1.0 g (93%). 1HNMR (CDCl3): 1.45 (s, 9H, Boc), 1.90 (dd, 1H), 2.34 (m, 1H), 3.40-3.62 (m, 3H), 4.00 (m, 2H), 4.28 (bs, 1H) and 4.44 (m, 1H).
