Yield:-
Reaction Conditions:
palladium
Steps:
5 Indazole-3-Carboxylic Acid
Preparation 5 Indazole-3-Carboxylic Acid A mixture of 4,5,6,7-tetrahydroindazole-3-carboxylic acid ethyl ester (21.0 g, 108 mmol), 5% palladium on carbon (7.0 g solid, 3.29 mmol of Pd), and 210 mL of cymene was heated to reflux for 38 hours. At this point complete conversion to the indazole-3-carboxylic acid ethyl ester was shown by TLC (silica gel, 3:1 ethyl acetate-heptane). The reaction was cooled to 120° C. and the 5% palladium on carbon was removed by filtration.
