(S)-2-[4-amino-5-(4-phenoxy-phenyl)-pyrrolo[2,3-d]pyrimidin-7-ylmethyl]-pyrrolidine-1-carboxylic acid tert-butyl ester → (S)-5-(4-phenoxy-phenyl)-7-pyrrolidin-2-ylmethyl-7H-pyrrolo[2,3-d]pyrimidin-4-ylamine

Participants

Reaction Steps

To a solution of (S)-2-[4-amino-5-(4-phenoxy-phenyl)-pyrrolo[2,3-d]pyrimidin-7-ylmethyl]-pyrrolidine-1-carboxylic acid tert-butyl ester (500 mg, 1.03 mmol) in 10 ml of DCM, TFA (10 ml) was added. The reaction mixture was stirred at RT for 2 h. The mixture was concentrated to give (S)-5-(4-phenoxyphenyl)-7-pyrrolidin-2-ylmethyl-7H-pyrrolo[2,3-d]pyrimidin-4-ylamine (400 mg), which was subjected to the next step without any further purification.
