2-propyl-2-(1H-pyrrolo[2,3-b]pyridine-5-carbonyl)-pyrrolidine-1-carboxylic acid tert-butyl ester → (2-propyl-pyrrolidin-2-yl)-(1H-pyrrolo[2,3-b]pyridin-5-yl)-methanone

Participants

Reaction Steps

A solution of 2-propyl-2-(1H-pyrrolo[2,3-b]pyridine-5-carbonyl)-pyrrolidine-1-carboxylic acid tert-butyl ester (0.240 g, 0.672 mmol) in 1N methanolic HCl (10.1 mL) was stirred at 20° C. under nitrogen for 18 hours. The reaction mixture was concentrated in vacuo then triturated with DCM (5 mL) and concentrated in vacuo to yield (2-propyl-pyrrolidin-2-yl)-(1H-pyrrolo[2,3-b]pyridin-5-yl)-methanone (0.215 g, 0.652 mmol, 97%) as a white powder and as a monohydrochloride salt, MS=258 [M+H]+.
