Procedure

To a solution of 100 mg of tert-butyl 5-amino-3-(3-fluorophenyl)-1H-1-indazolecarboxylate produced in Production Example I-26 and 0.1 ml of triethylamine in 5 ml tetrahydrofuran was added 55 mg of nicotinic acid chloride hydrochloride, and the mixture was stirred at room temperature for two days. After the completion of the reaction, the reaction mixture was treated with 5 N hydrochloric acid by the procedure of Production Example I-25-b, to give 62 mg of the title compound as a colorless powder.
