Ammonium formate → HCID 57901694, compound

Participants

Reaction Steps

A mixture of methyl 7-(benzylamino)-1H-pyrrolo[2,3-c]pyridine-2-carboxylate (3.2 g), ammonium formate (7.2 g), 10% palladium-carbon (50% containing water, 3.2 g) and methanol (120 mL) was heated under reflux for 4 hr. Ammonium formate (6.0 g) was further added to the reaction solution, and the mixture was heated under reflux for 16 hr. The insoluble material was filtered off by passing the reaction solution through celite without cooling. The filtrate was concentrated and the obtained crystals were washed with methanol to give the title compound (1.62 g, yield 75%) as pale-yellow prism crystals. melting point not less than 300° C.
