実験手順

Potassium carbonate (25.1 mg, 0.182 mmol) and iodomethane (4.9 μL, 0.079 mmol) were added to a solution of 4-(2-fluorophenyl)-7-hydroxy-9H-carbazole-1-carboxamide (Example 40-1, 19.4 mg, 0.061 mmol) in DMSO (1 mL) and the mixture was stirred at rt. After 17 h, the mixture was diluted with EtOAc (30 mL), washed with saturated aqueous ammonium chloride (5 mL), water (2×5 mL), and brine (5 mL), dried and concentrated. The residue was purified by preparative HPLC to provide 4-(2-fluorophenyl)-7-methoxy-9H-carbazole-1-carboxamide (1.9 mg, 9%). 1H NMR (400 MHz, chloroform-d) δ 10.39 (1H, br. s.), 7.58 (1H, d, J=7.70 Hz), 7.44-7.55 (2H, m), 7.28-7.39 (2H, m), 7.07-7.22 (2H, m), 7.00 (1H, d, J=2.20 Hz), 6.65 (1H, dd, J=8.80, 2.42 Hz), 6.57 (2H, br. s.), 3.88 (3H, s). Mass spectrum m/z 335.0 (M+H)+.
