Reaction Steps

To a solution of methyl 2-methyl-2-[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]propanoate (Example 174; 63 mg, 0.12 mmol) in 1:2 THF:H2O (3 mL:6 mL) was added lithium hydroxide monohydrate (8.0 mg, 0.19 mmol). The mixture was heated at 60° C. for 5 h. The THF was removed under reduced pressure, and the resulting solution was acidified to neutral pH with 10% aq. HCl. The solution was then extracted with EtOAc. The organic layers were combined, dried, and concentrated. The crude residue was purified (FCC) to give the title compound (37 mg, 60%). MS (ESI): mass calcd. for C27H30F3N5O2, 513.24; m/z found, 514.1 [M+H]+. 1H NMR (CD3OD): 8.45-8.42 (m, 1H), 8.01 (dd, J=7.9, 1.7 Hz, 1H), 7.69-7.63 (m, 2H), 7.38-7.33 (m, 2H), 7.13-7.09 (m, 1H), 3.57-3.50 (m, 4H), 3.21-3.16 (m, 2H), 3.13-3.08 (m, 2H), 3.01-2.93 (m, 1H), 1.57 (s, 6H), 1.28 (d, J=6.9 Hz, 6H).
