Reaction Steps

To a solution of 3-oxo-3,4-dihydro-2H-pyrido[3,2-b][1,4]oxazine-6-carbaldehyde (153 mg, 0.858 mmol) in DMF (1.36 mL) was added 2-(6-methoxy-[1,5]naphthyridin-4-yl)-4,5,6,7-tetrahydro-2H-indazol-5-ylamine (84.4 mg, 0.286 mmol). The reaction mixture was stirred overnight at RT. NaBH4 (37.6 mg, 0.572 mmol) was then added and the suspension was stirred for 1 h at RT. The reaction mixture was diluted with CH3OH and poured into 1 N NaOH. The organic layer was separated, washed with brine (4×), dried (Na2SO4), filtered, and concentrated. The crude material was purified by basic reverse phase HPLC to provide 4.6 mg (3.5%) of the title compound. MS (ESI): exact mass calculated for C24H23N7O3, 457.19; m/z found, 458.3 [M+H]+. 1H NMR (500 MHz, CDCl3): 9.09 (s, 1H), 8.75 (d, J=5.1, 1H), 8.25 (d, J=9.1, 1H), 8.14 (d, J=5.1, 1H), 7.19 (d, J=8.0, 1H), 7.17 (d, J=9.1, 1H), 6.95 (d, J=8.0, 1H), 4.62 (s, 2H), 4.09 (s, 3H), 3.92 (s, 2H), 3.09-2.98 (m, 3H), 2.83-2.77 (m, 1H), 2.56 (dd, J=14.6, 7.9, 1H), 2.17-2.14 (m, 1H), 1.89-1.82 (m, 1H), 1.24 (s, 1H).
