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 1h. The reaction was concentrated in-vacuo and partitioned between 1N 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 (114 mg).
