Procedure

A solution of 3-(3-aminophenyl)-4-bromo-1-methylpyrazole (35 mg, 0.14 mmol) and triethylamine (23 μL, 0.17 mmol) in DMF (0.5 mL) was added in one portion to a stirred solution of 4-trifluoromethoxyphenylacetic acid (31 mg, 0.14 mmol), HBTU (53 mg, 0.14 mmol) and HOBT (19 mg, 0.14 mmol) in DMF (1 mL). The mixture was heated at 70° C. for 24 h and then quenched with aqueous sodium bicarbonate solution. Ethyl acetate was added and the organic phase separated, washed with water (×3), brine, dried (MgSO4) and evaporated. Chromatography on flash silica (50%EtOAc/hexane) gave the title compound as a colourless solid (43 mg, 68%), m.p. 141.2-142.5° C. (EtOAc/hexane).
