Reaction Steps

A solution of 3-amino-1-(4-chlorobenzyl)homopiperidine (24 mg, 0.10 mmol) and 4-benzoylbutyric acid (1.2 equiv.) in CHCl3 (1 mL) was treated with EDCI (23 mg), HOBt (16.2 mg) and Et3N (15.2 μL), and stirred at 25° C. for 16 h. The reaction mixture was diluted with CH2Cl2 (0.5 mL), washed with 2 N aqueous NaOH solution (2×0.75 mL), dried by filtration through a PTFE membrane and concentrated to afford 1-(4-chlorobenzyl)-3-{(4-benzoylbutyryl)amino}homopiperidine (compound No. 994) (43 mg, 99%): The purity was determined by RPLC/MS (98%); ESI/MS m/e 413 (M++H, C24H29ClN2O2)
