実験手順

A solution of 9-chloro-2-(1-isopropyl-1H-1,2,4-triazol-5-yl)-5,6-dihydroimidazo[1,2-d]pyrido[3,4-f][1,4]oxazepine 317 (35.0 mg, 0.106 mmol) in Methanol (1.91 mL, 47.1 mmol) was added Triethylamine (0.0147 mL, 0.106 mmol) and Palladium (0.0113 g, 0.0106 mmol). The reaction was stirred overnight at room temperature under H2 atm. The reaction was filtered thru celite. The solute was concentrated then diluted with EtOAc, wash with H2O. The organic layer was dried Na2SO4, concentrated. The crude product was purified by isco column to give 364. MS: (ESI+)=297.1. 1H NMR (400 MHz, DMSO) δ 9.49 (s, 1H), 8.36 (d, J=5.7 Hz, 1H), 7.99 (s, 1H), 7.92 (s, 1H), 7.05 (d, J=5.7 Hz, 1H), 5.90 (dt, J=13.2, 6.5 Hz, 1H), 4.59 (dt, J=26.2, 13.1 Hz, 4H), 1.50 (d, J=6.6 Hz, 6H)
