実験手順
A mixture of 5-methoxy-2-[(1-phenyl-1H-pyrazol-5-yl)amino]benzoic acid (made by Ullmann reaction as described in Example 1, 42.0 mg, 0.14 mmol), benzylamine hydrochloride (23.4 mg, 0.16 mmol), EDCI (31.2 mg, 0.16 mmol), HOBT (22.0 mg, 0.16 mmol), and triethylamine (0.066 mL, 0.48 mmol) in DMF (3 mL) was stirred at rt for 16 h. The reaction was quenched with water (20 mL) and extracted with ethyl acetate (10 mL). The organic layer was washed with brine, dried over Na2SO4, filtered, and concentrated under reduced pressure. Flash chromatography of the residue over silica gel, using 20% ethyl acetate/hexane, gave the title compound (16.1 mg, 30%) as a white solid. 1H NMR (300 MHz, DMSO-d6) δ 9.72 (s, 1H), 9.14 (t, 1H), 7.57 (d, 1H), 7.38-7.51 (m, 4H), 7.16-7.36 (m, 7H), 6.96-7.06 (m, 2H), 6.15 (s, 1H), 4.37 (d, 2H), 3.70 (s, 3H); ES-MS m/z 399.1 (MH+), HPLC RT (min) 3.72.
