Reaction Steps
A solution of 50 mg of tert-butyl 5-amino-3-(3-fluorophenyl)-1H-1-indazolecarboxylate produced in Production Example I-26, 26 mg of 4-pyridylacetic acid hydrochloride and 0.05 ml of triethylamine in 5 ml tetrahydrofuran was added 37 mg of 1,1′-carbonyldiimidazole as a condensing agent at room temperature. 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 11 mg of the title compound as a colorless powder.
