4-(3,4-dihydroquinolin-1(2H)-ylsulfonyl)benzoic acid (1) (100 mg, 0.32 mmol) was treated with 3-(4-fluorophenyl)-1H-pyrazol-5-amine (43 mg, 0.24 mmol) using method B. The residue was purified using flash chromatography eluting with 0-8% MeOH in EtOAc. The resulting solid was triturated with dichloromethane/hexanes to give 4-(3,4-dihydroquinolin-1(2H)-ylsulfonyl)-N-(3-(4-fluorophenyl)-1H-pyrazol-5-yl)benzamide as an off white solid. Yield: 36 mg (31%). 1H-NMR: 11.11 (s, 1H), 8.10 (d, J=8.5 Hz, 2H), 7.80 (dd, J=8.5, 5.5 Hz, 2H), 7.71 (d, J=8.0 Hz, 2H), 7.62 (d, J=8.5 Hz, 1H), 7.33-7.08 (m, 5H), 7.01 (br s, 1H), 3.83-3.79 (m, 2H), 2.45 (t, J=7.0 Hz, 2H), 1.66-1.58 (m, 2H).
