To a solution of 4-({ethyl-[7-(4-methanesulfonyl-benzoylamino)-1,2,3,4-tetrahydro-naphthalen-2-yl]-amino}-methyl)-piperidine-1-carboxylic acid tert-butyl ester (1.33 g, 2.3 mmol) in methylene chloride (30 mL) under a nitrogen atmosphere was added trifluoroacetic acid (10 mL). The reaction was stirred at room temperature for 30 min. and concentrated in-vacuo. The residue was partitioned between EtOAc (50 mL) and 10% aq. KOH (50 mL), the organic layer was separated, dried over MgSO4, filtered, and concentrated to afford N-[7-(ethyl-piperidin-4-ylmethyl-amino)-5,6,7,8-tetrahydro-naphthalen-2-yl]-4-methanesulfonyl-benzamide (1.02 g). [M+H]+=470.
