Procedure

The title compound was prepared from ({[({[(3S,11aR)-8-({[(2,4-difluorophenyl)methyl]amino}carbonyl)-3-methyl-5,7-dioxo-2,3,5,7,11,11a-hexahydro[1,3]oxazolo[3,2-a]pyrido[1,2-d]pyrazin-6-yl]oxy}methyl)oxy]carbonyl}oxy)acetic acid (64 mg, 0.119 mmol), (2-pyridinylmethyl)amine (0.02 mL, 0.179 mL), N,N-diisopropylethylamine (0.03 mL, 0.179 mL), and HATU (69 mg, 0.179 mmol), using a process similar to that described in example 16, step (a). Purification by silica gel chromatography yielded the title compound as a white solid. 1H NMR (CDCl3) δ 10.09 (m, 1H), 8.46 (d, J=5.2 Hz, 1H), 8.38 (s, 1H), 7.75 (m, 1H), 7.59 (m, 1H), 7.34-7.26 (m, 2H), 7.14 (m, 1H), 6.78 (m, 2H), 6.04 (d, J=6.8 Hz, 1H), 5.87 (d, J=6.8 Hz, 1H), 5.27-5.22 (m, 2H), 4.80-4.52 (m, 5H), 4.32-4.22 (m, 3H), 3.82 (m, 1H), 3.61 (m, 1H), 1.26 (d, J=6 Hz, 3H). ES+ MS: 628 (M+1).
