反応手順

To a solution of 4-methylsulfonylphenylacetic acid (100 mg, 0.467 mmol) in acetonitrile was added 1-hydroxybenzotriazole (76 mg, 0.56 mmol), 1-ethyl-3-(3-dimethylaminopropyl)carboiimide hydrochloride (108 mg, 0.56 mmol), triethylamine (0.143 mL, 1.03 mmol) and N1-ethyl-4-[(trifluoromethyl)sulfonyl]benzene-1,2-diamine (125 mg, 0.467 mmol). The mixture was stirred at room temperature for overnight. The reaction was extracted with ethyl acetate, washed with water and brine, dried, concentrated and recrystallized from ethyl acetate to give the title compound. 1H NMR (300 MHz, DMSO-d6) δ9.54 (br s, 1H, NH), 7.88 (d, J=8.3 Hz, 2H), 7.75 (d, J=2.1 Hz, 1H), 7.64 (dd, 1H), 7.61 (d, J=8.3 Hz, 2H), 6.90 (d, J=9.0 Hz, 1H), 6.70 (t, J=5.2 Hz, 1H, NH), 3.86 (s, 2H, CH2), 3.31 (s, 3H, CH3), 3.29 (m, 2H, NCH2CH3), 1.20 (t, J=7.1 Hz, 3H, NCH2CH3). MS 465 [M++1].
