Reaction Steps

A solution of 1-(4-chlorobenzyl)-4-{(valylamino)methyl}piperidine (20 mg, 0.059 mmol) in CH2Cl2 (0.60 mL) was treated with Et3N (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). The reaction mixture was stirred at 25° C. for 16 h. The resulting solution was diluted with CH2Cl2 (0.75 mL), washed with 2 N aqueous NaOH solution (2×0.75 mL) and dried by filtration through a PTFE membrane. Concentration afforded the 1-(4-chlorobenzyl)-4-[{N-(3-cyanobenzoyl)valyl}aminomethyl]piperidine (compound No. 619) (24.2 mg, 88%) which required no further purification: The purity was determined by RPLC/MS (85%); ESI/MS m/e 467 (M++H, C26H31ClN4O2).
