Procedure

To a solution of 4-(3-amino-4-cyanopyrazole-1-yl)benzoic acid ethyl ester (0.1 g) in tetrahydrofuran (4 mL) were added acetyl chloride (0.12 g) and pyridine (0.15 g), and this mixture was stirred at room temperature for 12 hours. This reaction mixture was poured into water, and the precipitated solid was collected by filtration. This obtained solid was washed with ethyl acetate, dried under reduced pressure at 50° C. to give the title compound (0.088 g).
