Procedure

racemic-4aS,6aS,14aS)-6-[2-(Acetylamino)ethyl]-N-[(2,4-difluorophenyl)methyl]-12-hydroxy-11,13-dioxo-1,2,3,4,4a,5,6,6a,7,11,13,14a-dodecahydropyrido[1′,2′:4,5]pyrazino[1,2-a]quinazoline-10-carboxamide. In a manner similar to that described in example Z-35, from racemic-N-[2-({[(1S,2S)-2-aminocyclohexyl]methyl}amino)ethyl]acetamide hydrochloride (82 mg, 0.349 mmol) and 16a (50 mg, 0.106 mmol) was prepared the title compound (24 mg, 36%). This material was deprotected in a second step similar to the procedure described in example Z-37. Thus, from racemic (4aS,6aS,14aS)-6-[2-(acetylamino)ethyl]-N-[(2,4-difluorophenyl)methyl]11,13-dioxo-12-[(phenylmethyl)oxy]-1,2,3,4,4a,5,6,6a,7,11,13,14a-dodecahydropyrido[1′,2′:4,5]pyrazino[1,2-a]quinazoline-10-carboxamide (24 mg, 0.0379 mmol) and 10% Pd/C (1 mg) was prepared the title compound as a white solid after purification by HPLC. 1H NMR (CDCl3) 12.59 (s, 1H), 10.44 (s, 1H), 8.35 (s, 1H), 7.32 (m, 1H), 6.79 (m, 2H), 5.86 (s, 1H), 4.78 (m, 1H), 4.61-4.50 (m, 3H), 4.30 (m, 1H), 3.35 (m, 1H), 3.18 (m, 1H), 2.96 (m, 1H), 2.76 (m, 2H), 2.48 (m, 1H), 2.19 (m, 1H), 1.89-1.23 (m, 12H): ES+ MS: 544 (M+1).
