Participants

Reaction Steps

To a stirred solution of 2-(4-(methylsulfonamidomethyl)phenyl)propanoic acid (37 mg, 0.144 mmol) and (1-(3-chlorophenyl)-3-(trifluoromethyl)-1H-pyrazol-5-yl)methanamine (44 mg, 0.158 mmol) in acetonitrile were added EDC (41 mg, 0.216 mmol), HOBt (29 mg, 0.216 mmol) and triethylamine (0.05 mL, 0.36 mmol). The reaction mixture was stirred for 15 h at room temperature. The residue dissolved in EtOAc and washed with water and brine. The organic layer was dried (MgSO4) and filtered. The solvent was removed in vacuo. The crude product was purified by CC. Example compound B5 (62 mg) was obtained in 84% yield.
