Procedure

To a solution 3-(2-methyl-2H-pyrazol-3-yl)-4-(2-[1,4]oxazepan-4-yl-ethoxy)-phenylamine (0.07 g, 0.2215 mmol) in 2.0 mL of DMA was added DIEA (0.057 g, 0.443 mmol), followed by m-trifluoromethyl benzoyl chloride (0.056 g, 0.266 mmol), and the reaction mixture was stirred at ambient temperature overnight. The reaction mixture was diluted to 5.0 mL with DMSO and purified by RP-HPLC. The proper fractions were collected and lyophilized to afford N-[3-(2-Methyl-2H-pyrazol-3-yl)-4-(2-[1,4]oxazepan-4-yl-ethoxy)-phenyl]-3-trifluoromethyl-benzamide as an off-white semisolid in 87% yield. LCMS m/z (%)=489 (M+H, 100). 1H NMR (400 MHz, DMSO-d6) δ: 10.5 (bs, 1H), 8.29 (s, 1H), 8.26 (d, J=7.94 Hz, 1H), 7.98 (d, J=7.83 Hz, 1H), 7.89 (dd, J=8.93 and 2.55 Hz, 1H), 7.79 (t, J=7.82 Hz, 1H), 7.72 (d, J=2.53 Hz, 1H), 7.49 (s, 1H), 7.26 (d, J=9.14 Hz, 1H), 6.31 (d, J=1.79 Hz, 1H), 4.29-4.43 (m, 2H), 3.69 (s, 3H), 3.55-3.64 (m, 5H), 3.01-3.18 (m, 5H), 1.8-2.1 (m, 2H).
