To an ice cold solution of 4-{[(7-hydroxy-1,2,3,4-tetrahydro-naphthalen-2-yl)-propyl-amino]-methyl}-piperidine-1-carboxylic acid tert-butyl ester (300 mg, 0.75 mmol) in methylene chloride (30 mL) under a nitrogen atmosphere was added triethylamine (0.16 ml, 1.125 mmol) followed by trifluoromethanesulfonyl chloride (0.08 ml, 0.78 mmol). The reaction was stirred in the ice bath for 30 min. and then added to water (60 ml). The organic layer was separated, dried over MgSO4, filtered, and concentrated. Chromatography with 40% acetone in hexanes affords 4-{[propyl-(7-trifluoromethanesulfonyloxy-1,2,3,4-tetrahydro-naphthalen-2-yl)-amino]-methyl}-piperidine-1-carboxylic acid tert-butyl ester (220 mg).
