Triethylamine (0.011 mL, 0.077 mmol), m-cyanobenzoic acid (28 mg, 0.071 mmol), EDCI (13 mg, 0.065 mmol) and HOBt (9 mg, 0.065 mmol) were added to a dichloromethane (0.60 mL) solution of 1-(4-chlorobenzyl)-4-[(valylamino)methyl]piperidine (20 mg, 0.059 mmol). The resulting reaction mixture was stirred at 25° C. for 16 hours, and the obtained solution was diluted with dichloromethane (0.75 mL), washed with a 2 M aqueous solution of NaOH (0.75 mL×2) and dried by filtration through a PTFE membrane. The dried solution was concentrated to thereby afford 1-(4-chlorobenzyl)-4-[[N-(3-cyanobenzoyl)valyl]aminomethyl]piperidine (Compd. No. 619) (24.2 mg, 88%). Further purification was not required for the resulting compound. The purity was determined by RPLC/MS (85%). ESI/MS m/e 467 (M++H, C26H31ClN4O2).
