反応手順
N-(tert-Butoxycarbonyl )-O-benzylhydroxylamine (1.43 g, 6.40 mmol) was alkylated with (6) (3.00 g, 5.68 mmol) using NaH (80%, 0.19 g, 6.33 mmol) in DMF (100 mL), following the procedure used for (4). Column chromatography on silica gel with 4:1 hexane/EtOAc yielded 3.0 g (74%) of (7) as an oil: NMR δ 1.50 (s, 9 H), 1.40-1.85 (m, 12 H), 2.20-2.50 (m, 6 H), 3.27-3.70 (m, 6 H), 4.75 (s, 6 H), 7.33 (s, 15 H). Anal. (C41H54N4O7) C, H, N.
