Procedure
In a manner similar to that described in example Z-35, from 16 (15 mg, 0.034 mmol) and [(3S)-3-Aminobutyl][2-(methyloxy)ethyl]amine bis hydrochloride, (19 mg, 0.087 mmol), (4S,12aS)—N-[(4-fluorophenyl)methyl]-4-methyl-1-[2-(methyloxy)ethyl]-6,8-dioxo 7-[(phenylmethyl)oxy]-1,2,3,4,6,8,12,12a-octahydropyrido[1′,2′:4,5]pyrazino[1,2-a]pyrimidine-9-carboxamide was prepared as a white solid after silica gel chromatography (1-12% methanol/dichloromethane). This material was deprotected in a second step similar to that described in example Z-37 to give the title compound as a yellow solid (9 mg, 60%, 2 steps). 1H NMR (CDCl3) δ 12.56 (s, 1H), 10.51 (m, 1H), 8.29 (s, 1H) 7.32 (m, 2H), 6.98 (m, 2H), 5.03 (m, 1H), 4.65-4.59 (m, 2H), 4.53 (m, 1H), 4.2 (m, 1H), 3.61-3.40 (m, 2H), 3.34-3.13 (m, 3H), 3.08 (m, 1H), 2.94-2.84 (m, 2H), 2.68 (m, 1H), 2.07 (m, 1H), 1.50 (m, 1H), 1.35 (d, J=7.2 Hz, 3H), 1.14 (m, 1H); ES+ MS: 459 (M+1).
