Trifluoroacetic acid → Trifluoro-methanesulfonic acid 7-(piperidin-4-ylmethyl-propyl-amino)-5,6,7,8-tetrahydro-naphthalen-2-yl ester

Participants

Reaction Steps

To a solution of 4-{[propyl-(7-trifluoromethanesulfonyloxy-1,2,3,4-tetrahydro-naphthalen-2-yl)-amino]-methyl}-piperidine-1-carboxylic acid tert-butyl ester, (220 mg, 0.41 mmol) in methylene chloride (5.0 mL) under an inert atmosphere was added trifluoroacetic acid (1.0 ml). The reaction was stirred at room temperature for 1 h. The reaction was concentrated in-vacuo and partitioned between 1 N NaOH (20 ml) and EtOAc (30 ml). The organic layer was separated, dried (MgSO4), and concentrated to afford trifluoro-methanesulfonic acid 7-(piperidin-4-ylmethyl-propyl-amino)-5,6,7,8-tetrahydro-naphthalen-2-yl ester (114mg).
