Procedure

A solution of 1-(4-fluorophenyl)pyrazol-4-amine (0.59 g, 3.3 mmol) in formic acid (15 mL) was heated at 80° C. for 2 h. The reaction mixture was cooled to room temperature, concentrated in vacuo, and purified by flash chromatography (SiO2, 0-100% EtOAc/CH2Cl2 gradient elution) to give N-[1-(4-fluorophenyl)pyrazol-4-yl]formamide (0.490 g, 71%).
