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 (.times.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).
