Procedure
A solution of (1-(4-{(S)-1-[(R)-1-(4-Methoxy-phenyl)-ethyl]-pyrrolidin-2-yl}-pyridin-2-yl)-2,3-dihydro-1H-indole (140 mg, 0.35 mmol) in TFA (10 mL) is heated in microwave at 100° C. for 30 min and concentrated down to give crude 1-((S)-4-pyrrolidin-2-yl-pyridin-2-yl)-2,3-dihydro-1H-indole (6), which is used in next step without further purification.
