3-(4-{(S)-1-[(R)-1-(4-Methoxy-phenyl)-ethyl]-pyrrolidin-2-yl}-pyridin-2-yl)-indole-1-carboxylic acid tert-butyl ester → 3-((S)-4-pyrrolidin-2-yl-pyridine-2-yl)-1H-indole

Participants

Reaction Steps

A solution of 3-(4-{(S)-1-[(R)-1-(4-Methoxy-phenyl)-ethyl]-pyrrolidin-2-yl}-pyridin-2-yl)-indole-1-carboxylic acid tert-butyl ester (160 mg, 0.31 mmol) in TFA (5 mL) is heated in microwave at 100° C. for 30 min and concentrated down to give crude 3-((S)-4-pyrrolidin-2-yl-pyridine-2-yl)-1H-indole (15), which is used in next step without further purification.
