Reaction Steps

Methyl 3-pyridin-4-yl-1H-indazole-5-carboxylate (305 mg, 1.204 mmol) and KOH (88 mg, 1.566 mmol) were stirred in THF (9 mL)/MeOH (1.5 mL)/water (1.5 mL) at 70° C. for 24 hours. Additional KOH (87 mg, 1.551 mmol) was added and stirring at 70° C. continued for 20 hours. Room temperature was attained and the solvent was removed in vacuo to give potassium 3-(pyridin-4-yl)-1H-indazole-5-carboxylate as a brown solid (˜67 wt %).
