Reaction Steps

racemic-(4aR,6aR,14aS)—N-[(2,4-Difluorophenyl)methyl]-11,13-dioxo-12-[(phenylmethyl)oxy]-1,3,4,4a,5,6a,7,11,13,14a-decahydro-2H-pyrido[1′,2′:4,5]pyrazino[1,2-a][3,1]benzoxazine-10-carboxamide (13 mg, 0.0236 mmol) was dissolved in tetrahydrofuran and 10 w.t. % Pd/C (13 mg) was added. Hydrogen was passed through the solution several times and the mixture was stirred at 1 atm hydrogen for 18 hours until the reaction was determined complete by TLC (5% methanol/dichloromethane). The mixture was filtered through Celtite, eluting with methanol/chloroform and the filtrate was concentrated under reduced pressure and purified by HPLC to yield the title compound (7.3 mg, 73%) 1H NMR (CDCl3) δ 12.45 (m, 1H), 10.38 (s, 1H), 8.30 (s, 1H), 7.32 (m, 1H), 6.83-6.76 (m, 2H), 5.23 (m, 1H), 4.75 (m, 1H), 4.63 (m, 2H), 4.26 (m, 1H), 4.12-4.01 (m, 2H), 3.83 (m, 1H), 2.30 (m, 1H), 1.91 (m, 1H), 1.80 (m, 1H), 1.67-1.40 (m, 5H), 1.20 (m, 1H); ES+ MS: 460 (M+1).
