Procedure

To a stirred solution of 2-(3-fluoro-4-(methylsulfonylmethyl)phenyl)propanoic acid (68 mg, 0.231 mmol) and (1-(3-chlorophenyl)-3-(trifluoromethyl)-1H-pyrazol-5-yl)methanamine (60 mg, 0.231 mmol) in THF (1.8 mL) were added O-(1H-Benzotriazol-1-yl)-N,N,N′,N′-tetramethyluronium tetrafluorborat (73 mg, 0.231 mmol), 1-hydroxybenzotriazole (30 mg, 0.231 mmol) and N-ethyldiisopropylamine (0.078 mL, 0.462 mmol). The reaction mixture was stirred for 48 h at room temperature, concentrated in vacuo and the residue was purified by CC (eluent: ethyl acetate/cyclohexane (3:2)) to give N-[[2-(3-Chlorophenyl)-5-(trifluoromethyl)-2H-pyrazol-3-yl]-methyl]-2-[3-fluoro-4-(methylsulfonyl-methyl)-phenyl]-propionamide (83 mg, 69%).
