Reaction Steps

1-(3-Chloro-5-trifluoromethylpyridin-2-yl) -5,6-dinitroindazole [Compound No. 28] (8.0 g) was dissolved in ethyl acetate (100 g) and reduced with 10% Pd-C (0.1 g) at ordinary temperature under atmospheric pressure for 8 hours. After completion of the reaction, the reaction mixture was filtered to remove the Pd-C, and the filtrate was concentrated under reduced pressure to give 1-(3-chloro-5-trifluoromethylpyridin-2-yl)-5,6-diaminoindazole (7.2 g).
