Reaction Steps

To a solution of 1-[4-({2-(1-methylethyl)-7-[3-(trifluoromethyl)pyridin-2-yl]-6,7,8,9-tetrahydro-5H-pyrimido[4,5-d]azepin-4-yl}amino)phenyl]ethanone (Example 96; 37 mg, 0.079 mmol) in MeOH was added NaBH4 (4.1 mg, 0.11 mmol). The mixture was stirred at rt for 4 h, then concentrated. The residue was redissolved in water and extracted with EtOAc. The organic layers were combined, dried, and concentrated. The crude residue was purified (FCC) to give the title compound (32.1 mg, 86%). MS (ESI): mass calcd. for C25H28F3N5O, 471.22; m/z found, 472.2 [M+H]+. 1H NMR (CDCl3): 8.40-8.38 (m, 1H), 7.87 (dd, J=7.8, 1.8 Hz, 1H), 7.67-7.64 (m, 2H), 7.38-7.34 (m, 2H), 6.97-6.92 (m, 1H), 6.51 (s, 1H), 4.93-4.88 (m, 1H), 3.69-3.60 (m, 4H), 3.24-3.18 (m, 2H), 3.06-2.98 (m, 1H), 2.98-2.94 (m, 2H), 1.76 (d, J=3.6 Hz, 1H), 1.52 (d, J=6.4 Hz, 3H), 1.31 (d, J=6.9 Hz, 6H).
