A solution of {4-[3-(trifluoromethyl)-4,5,6,7-tetrahydro-1H-indazol-1-yl]phenyl}acetic acid (65 mg, 0.2 mmol) in dichloromethane (2 ml) was treated with 1,1′-carbonyldiimidazole (32.5 mg, 0.2 mmol) in one portion at room temperature. Stirring was continued at room temperature for 15 minutes. Then 2-phenylpyrrolidine (29 mg, 0.2 mmol) was added and stirring continued for 1 hour. Most of the solvent was removed under reduced pressure and the crude product was further purified by MDAP to give the title compound (55 mg, 61%).
