Procedure

To 4-chlorobenzoyl chloride (15 mg, 0.08 mmol) in CH2Cl2 (1 mL) was added dropwise a solution of 3-(3-aminophenyl)-4-bromo-1-methylpyrazole (21 mg, 0.08 mmol) and triethylamine (12 μL, 0.08 mmol) in CH2Cl2 (0.5 mL). The mixture was stirred for 16 h and concentrated. Chromatography on flash silica (50% EtOAc/hexane) gave the title compound as a colourless solid (23 mg, 72%), m.p. 184.4-184.8° C. (EtOAc/hexane).
