Yield: 89%
Reaction Conditions:
in tetrahydrofuran at 10 - 20; for 2 h;
Steps:
5
Intermediate 5 :tert-butyl 5-oxo-l,4-diazepane-l-carboxylate; To a stirred solution of commercially available l,4-diazepan-5-one (3.3 g, 28.94 mmol) in THF cooled to 10°C, was added di-tert-butyl dicarbonate(9.5 g, 43.42 mmol) and the resultant reaction mixture was stirred at RT for 2 h. The reaction mixture was concentrated under reduced pressure and the resulting residue was washed with n-pentane (50 mL) to afford the title compound as a solid (5.5 g, 89%).:H NMR (300 MHz, DMSO) δ = 7.62 (s, 1H), 3.45-3.40 (m, 4H), 3.12-3.08 (m, 2H), 2.43-2.39 (m, 2H).
