実験手順

Sodium cyanoborohydride (140 mmol) in methanol (0.4 mL) was added to a mixture of 4-[(N-(2-amino-5-chlorobenzoyl)glycyl)aminomethyl]piperidine (0.10 mmol), 4-ethoxybenzaldehyde (0.10 mmol), acetic acid (0.050 mL), and methanol (1.6 mL). The reaction mixture was stirred at 60° C. for 14 h. The reaction mixture was loaded onto Varian™ SCX column and washed with CH3OH (20 mL). Product was eluted using 2 N NH3 in CH3OH (6 mL) and concentrated. Preparative TLC (SiO2, AcOEt/CH3OH 5:1) afforded 4-[{N-(2-amino-5-chlorobenzoyl)glycyl}aminomethyl]-1-(4-ethoxybenzyl)piperidine (Compound No. 1429) and 1-(4-ethoxybenzyl)-4-[{N-(2-(4-ethoxybenzyl)amino-5-chlorobenzoyl)glycyl)aminomethyl]piperidine (Compound No. 1433).
