Ammonium formate → HCID 22934104, compound

Participants

Reaction Steps

Ammonium formate (0.363 g) and 10% Pd—C (0.074 g) were added to a suspension of the N-(1-benzylpiperidin-3-yl)-1H-indazole-5-carboxamide (0.357 g, 1.06 mmol) obtained in Example 138 in ethanol (10 ml), and the resulting mixture was stirred for 4 hours with heating under reflux. The resulting solution was filtered by the use of Celite and then the solvent was distilled off from the filtrate to obtain a solid. The solid obtained was suspended in ethyl acetate, stirred to be washed, collected by filtration and dried under reduced pressure to obtain N-(3-piperidinyl)-1H-indazole-5-carboxamide (0.250 g, 96%).
