Procedure

The title compound was made in two steps using a similar process to that described in example Z-2. 16 (84 mg, 0.13 mmol) and {2-[(2S)-2-Pyrrolidinyl]ethyl}amine (150 mg, 1.3 mmol) were reacted in dichloromethane (2 mL) with acetic acid to give (3aS,13aS)—N-[(4-fluorophenyl)methyl]-7,9-dioxo-8-[(phenylmethyl)oxy]-1,2,3,3a,4,5,7,9,13,13a-decahydropyrido[1′,2′:4,5]pyrazino[1,2-a]pyrrolo[1,2-c]pyrimidine-10-carboxamide (86 mg, 90%). This material was hydrogenated in a second step as described in example Z-2 to give (3aS,13aS)—N-[(4-Fluorophenyl)methyl]-8-hydroxy-7,9-dioxo-1,2,3,3a,4,5,7,9,13,13a-decahydropyrido[1′,2′:3,4]pyrazino[1,2-a]pyrrolo[1,2-c]pyrimidine-10-carboxamide. (63 mg, 88%) as a white solid. 1H NMR (CDCl3/CD3OD) δ 10.45 (m, 1H), 8.23 (s, 1H), 7.35 (m, 2H), 6.94 (t, J=8.8 Hz, 2H), 4.63 (m, 1H), 4.58-4.48 (m, 2H), 4.33 (dd, J=13.6, 3.6 Hz, 1H), 4.21 (m, 1H), 4.11 (m, 1H), 2.98 (m, 1H), 2.85 (td, J=13.2, 3.2 Hz, 1H), 2.41 (m, 1H), 2.29 (m, 1H), 1.92 (m, 1H), 1.83-1.75 (m, 3H), 1.54-1.35 (m, 2H); ES+ MS: 427 (M+1).
