1H-indazole-6-carboxylic acid Chemical Properties,Uses,Production
Uses
1H-Indazole-6-carboxylic Acid is used as a reagent to synthesize azabicyclic aryl amides, which act as α7 nicotinic acetylcholine receptor agonists.
Preparation
Synthesis of 1H-indazole-6-carboxylic acid, H2L3: MeL3Ac (1.0 g; 4.6 mmol) was dissolved in 40 mL THF, and this solution was added to a 40 mL aqueous solution of lithium hydroxide (5.0 g; 210 mmol). The resulting suspension was heated at reflux with vigorous stirring overnight, after which time the solution was concentrated under vacuum to remove the organic phase. The resulting solution was filtered, adjusted to pH 3 with conc. HCl, to precipitate the product as a pale brown solid, which was filtered, washed with water and dried under vacuum.
