Trifluoroacetic acid → 5-(2-fluoro-4-phenoxy-phenyl)-7-pyrrolidin-2-ylmethyl-7H-pyrrolo[2,3-d]pyrimidin-4-ylamine

Participants

Reaction Steps

To a solution of 2-[4-amino-5-(2-fluoro-4-phenoxy-phenyl)-pyrrolo[2,3-d]pyrimidin-7-ylmethyl]-pyrrolidine-1-carboxylic acid tert-butyl ester (400 mg, 0.79 mmol) in 10 ml of DCM, was added TFA (10 ml). The reaction mixture was stirred at RT for 2 h. The mixture was then concentrated to give 5-(2-fluoro-4-phenoxy-phenyl)-7-pyrrolidin-2-ylmethyl-7H-pyrrolo[2,3-d]pyrimidin-4-ylamine (320 mg), which was used in the next step without any further purification.
