A solution of 4-[{N-(3-(trifluoromethyl)benzoyl)glycyl}aminomethyl]piperidine (19.9 mg, 0.058 mmol) in CH3CN (1.0 mL) and (piperidinomethyl)polystyrene (55 mg, 2.7 mmol base/g resin) were added to a solution of 3-(trifluoromethoxy)benzyl bromide (12.3 mg, 0.048 mmol) in CH3CN (1.0 mL). The reaction mixture was stirred at 60° C. for 2.5 h. Phenyl isocyanate (6.9 mg, 0.048 mmol) was added to the cooled reaction mixture 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 off using 2 N NH3 in CH3OH (6 mL) and concentrated to afford 1-{3-(trifluoromethoxy)benzyl}-4-[{N-(3-(trifluoromethyl)benzoyl)glycyl}aminomethyl]piperidine (compound No. 927) (22.8 mg, 91%) as a pale yellow oil: The purity was determined by RPLC/MS (99%); ESI/MS m/e 518.1 (M++H, C24H25F6N3O3).
