Participants

Reaction Steps

To a solution of the 4-({ethyl-[7-(2,2,2-trifluoro-acetylamino)-1,2,3,4-tetrahydro-naphthalen-2-yl]-amino}-methyl)-piperidine-1-carboxylic acid tert-butyl ester (800 mg, 1.7 mmol) in methylene chloride (20 mL) under an inert atmosphere was added trifluoroacetic acid (5 mL) and the solution was allowed to stir at room temperature for 1 h. The reaction was concentrated in vacuo and partitioned between 10% KOH and EtOAc. The organic layer was washed with brine, dried (MgSO4), and concentrated to afford N-[7-(ethyl-piperidin-4-ylmethyl-amino)-5,6,7,8-tetrahydro-naphthalen-2-yl]-2,2,2-trifluoro-acetamide as an oil which was used directly for the next step.
