DIPEA (167.7 mg, 1.29 mmol) was added to a stirred solution of [(5-phenyl-1H-pyrazole-3-carbonyl)-amino]-acetic acid (106 mg, 0.43 mmol) in DMF (4 mL) followed by HOBt (70.13 mg, 0.52 mmol) and EDCI (99.5 mg, 0.52 mmol). After 2 minutes of stirring, 3-(3-trifluoromethyl-phenoxy)-pyrrolidine (100 mg, 0.43 mmol) was added and the resulting mixture was stirred at room temperature overnight. Cold water was added and the precipitate was collected to afford 122 mg (61.5% Yield) of 5-phenyl-1H-pyrazole-3-carboxylic acid {2-oxo-2-[3-(3-trifluoromethyl-phenoxy)-pyrrolidin-1-yl]-ethyl}-amide. LC/MS [M+H]+: 459.16, 96.52%. 1H NMR (300 MHz, DMSO-d6): δ 13.8 (s, 1H), 8.05 (bs, 1H), 7.8 (db, 2H), 7.7-7.6 (m, 7H), 7.05 (bs, 1H), 5.4 (s, 1H), 5.3 (s, 1H), 4.1 (m, 2H), 3.9 (m, 1H), 3.8-3.6 (m, 3H), 3.4 (m, 1H), 2.3-2.0 (m, 2H).
