Procedure

1H-NMR (CDCl3,ppm) δ: 1.20-1.88(11 H,m), 2.20(3 H,s), 2.63(2 H,t,J=6.8 Hz), 2.60-2.32(4 H,m), 3.78(2 H,s), 7.25-7.36(5 H,m) (3) A suspension of N-benzyl-N-methyl-5-(4-aminomethylpiperidin-1-yl)-pentylamine (3.52 g), 4-amino-5-chloro-2-methoxybenzoic acid (2.34 g), dicyclohexylcarbodiimide (2.39 g), 1-hydroxybenzotriazole (1.57 g) and triethylamine (2.35 g) in N,N-dimethylformamide (40 ml) was stirred at room temperature for 12 hr. The solvent was evaporated, and water was added to the residue, which was followed by extraction with chloroform. The organic layer was washed with brine, dried and the solvent was evaporated under reduced pressure. The obtained residue was purified by silica gel column chromatography to give 0.86 g of 4-amino-5-chloro-2-methoxy-N-((1-(5-(N-benzyl-N-methylamino)pentyl)piperidin-4-yl)methyl)-benzamide.
