반응 단계

To N-[4-methyl-3-(9H-pyrimido[4,5-b]indol-7-yl)phenyl]-3-(trifluoromethyl)benzamide (442 mg, 0.990 mmol) was added 1,4-dioxane (2.0 mL) and water (2.0 mL) and sodium hydroxide (790 mg, 19.8 mmol). The resulting mixture was heated to 100° C. until LCMS indicated complete hydrolysis, typically 14-16 hours. The reaction was cooled to ambient temperature and the solvents were removed by evaporation. The residue was washed with water and the remaining solid was recovered by filtration, washed with additional water, and dried under reduced pressure to give the product (207 mg, 76%). 1H NMR (300 MHz, DMSO): δ 9.42 (s, 1H), 8.90 (s, 1H), 8.22 (d, 1H), 7.39 (s, 1H), 7.23 (d, 1H), 6.94 (d, 1H), 6.52 (m, 2H), 4.95 (s, 2H), 2.08 (s, 3H). MS (EI) m/z=275 (M+H).
