실험 절차

2-[4-Phenyl-1-(3-phenyl-propyl)-butylcarbamoyl]-piperidine-1-carboxylic acid tert-butyl ester (73) (6.77 g; 14.1 mmol) is dissolved in methylene chloride (60 mL) at ambient temperature. Trifluoroacetic acid (40 mL) is added in a slow stream, and the solution is stirred for 1.25 hours at ambient temperature. The solution is concentrated in vacuo at 40° C. The residue is dissolved in methylene chloride (300 mL) and poured onto saturated sodium bicarbonate solution. The pH is adjusted to 9 with saturated potassium carbonate solution. The mixture is shaken the layers separated. The water layer is extracted with methylene chloride (3×100 mL). The combined organic extracts are washed with water, dried over MgSO4, filtered, and concentrated in vacuo affording the desired product (5.34 g) as a white solid. ESMS: MH+ 379.2
