Reaction Steps

In 20 mL mixture of dichloromethane and trifluoroacetic acid 30%, was dissolved 2-{[(3,4-Dimethoxy-benzoyl)-naphthalen-2-ylmethyl-amino]-methyl}-pyrrolidine-1-carboxylic acid tert-butyl ester 1.1 g (2.18 mmol). After 1 hour at room temperature, saturated solution of sodium bicarbonate was added until basic pH, the mixture was extracted with dichlorometane, dried over magnesium sulfate, filtered and concentrated under vacuum, yield to 0.88 g. LC-MSD, m/z for: C25H28N2O3 [M+H]: 404.2. LC retention time on HPLC, C18 column gradient 20-95% acetonitrile with 0.1% TFA in 7 minutes: 1.37 min.
