Trifluoroacetic acid → [5-(1-Cyclopropyl-piperidin-4-yloxy)-1H-pyrrolo[2,3-b]pyridin-2-yl]-morpholin-4-yl-methanone

Participants

Reaction Steps

The solution of 0.16 g (0.34 mmol) 5-(1-cyclopropyl-piperidin-4-yloxy)-2-(morpholine-4-carbonyl)-pyrrolo[2,3-b]pyridine-1-carboxylic acid tert-butyl ester in 2 ml dichloromethane was cooled down to 0° C. and treated with 0.52 ml (0.8 g, 6.8 mmol) trifluoroacetic acid. The cooling bath was removed and after 1 hour at room temperature the solution was evaporated and the residue was flash-chromatographed on silica gel with dichloromethane:methanol:ammonia (9:1:0.1 v/v) as eluant to give 0.1 g (83%) of the desired compound as a colorless solid.
