To (S)-N-[2-(2,3-dihydrobenzofuran-5-yl)-1-methylethyl]-N-ethyl-[1-(tert-butoxycarbonyl)piperidin-4-ylmethyl]amine (3.78 grams, 9.4 mmol) was added 20% trifluoroacetic acid (50 ml) in dichloromethane. The solution was stirred at room temperature for 4 hours. The solution was concentrated under reduced pressure and the residue was partitioned between dichloromethane and 1N sodium hydroxide. The organic layer was washed with water, dried over potassium carbonate and concentrated to give (S)-N-[2-(2,3-dihydrobenzofuran-5-yl)-1-methylethyl]-N-ethyl-(piperidin-4-ylmethyl)amine as an oil (2.42 grams, 85%), M+H 303.
