Procedure

To tert-butyl (8S,9aS)-8-[(5-cyclopropylpyrazin-2-yl)oxy]-5-oxohexahydro-1H-pyrrolo[1,2-a][1,4]diazepine-2(3H)-carboxylate (254 mg, 0.654 mmol, Part C) in methanol/dichloromethane (1:1, 1 mL) was added 4 N HCl solution in dioxane (3 mL). The mixture was stirred at room temperature for three hours and then concentrated to give 212 mg (100% yield) of the title compound as a solid which was used without purification. 1H NMR (400 MHz, DMSO-d6) δ ppm 0.82 (m, 2H), 0.96 (m, 2H), 2.10 (m, 2H), 2.66 (m, 1H), 3.10 (m, 3H), 3.40 (m, 2H), 3.65 (m, 2H), 4.22 (m, 1H), 4.40 (m, 1H), 5.38 (m, 1H), 8.15 (d, J=1 Hz, 1H), 8.19 (d, J=1 Hz, 1H), 9.38 (br s, 1H), 9.50 (br s, 1H); MS (ESI) m/z 289.0 (M+H)+.
