(5aS,14aS)-N-[(2,4-Difluorophenyl)ethyl)methyl]-11-hydroxy-10,12-dioxo-1,2,3,4,5a,6,10,12,14,14a-decahydropyrido[1,2-a]pyrido[1′,2′:3,4]imidazo[1,2-d]pyrazine-9-carboxamide. In a manner similar to that described in example Z-37, from (5aS,14aS)-N-[(2,4-difluorophenyl)methyl]-10,12-dioxo-11-[(phenylmethyl)oxy]-1,2,3,4,5a,6,10,12,14,14a-decahydropyrido[1,2-a]pyrido[1′,2′:3,4]imidazo[1,2-d]pyrazine-9-carboxamide (18 mg, 0.0337 mmol) and 10 w.t.% Pd/C (catalytic amount) was prepared the title compound as a white solid (13 mg, 87%) after purification by HPLC, 1H NMR (CDCl3) δ 11.71 (br s, 1H), 10.36 (br s, 1H), 8.31 (s, 1H), 7.34 (m, 1H), 6.78 (m, 2H), 4.64-4.57 (m, 2H), 4.28 (m, 1H), 4.12 (m, 1H), 3.92-3.89 (m, 2H), 3.22 (m, 1H), 3.04 (m, 1H), 2.49 (m, 1H), 2.28 (m, 1H), 1.97-1.89 (m, 2H), 1.78 (m, 1H), 1.66-1.60 (m, 2H), 1.43-1.36 (m, 2H); ES+MS: 445 (M+1).
