실험 절차

A solution of 4-[{N-(3-(trifluoromethyl)benzoyl)glycyl}aminomethyl]piperidine (20.0 mg, 0.058 mmol) in CH3OH (1.0 mL) and NaBH3CN (16.5 mg) were added to a solution of 4-(dimethylamino)benzaldehyde (30.4 mg, 0.204 mmol) in 5% CH3COOH/CH3OH (1.0 mL). The reaction mixture was stirred at 60° C. for 19 h. The solvent was evaporated to afford a solid. CH3CN (2.0 mL) and phenyl isocyanate (6.9 mg, 0.048 mmol) were added to the solid and the mixture was stirred at 25° C. for 1 h. The reaction mixture was loaded onto Varian™ SCX column and washed with CH3OH (20 mL). Product was eluted using 2 N NH3-CH3OH (6 mL) and the eluant was concentrated to afford 1-(4-(dimethylamino)benzyl)-4-[{N-(3-(trifluoromethyl)benzoyl)glycyl}aminomethyl]piperidine (compound No. 937) as a pale yellow oil (13.5 mg, 49%): The purity was determined by RPLC/MS (87%); ESI/MS m/e 477.3 (M++H, C25H31F3N4O2).
