PROCEDURE

实验过程

A solution of 4-(3,4-dichlorobenzyl)-1-ethyl-1-{3-methyl-2-[3-(3,4,5-trimethoxy-phenyl)ureido]butyl}piperidinium iodide (0.2 g) in methanol (5 ml) was slowly passed through a column of Dowex 1x8-50 ion exchange resin (3 g). The eluted product was concentrated in vacuo to give 4-(3,4-dichlorobenzyl)-1-ethyl-1-{3-methyl-2-[3-(3,4,5-trimethoxyphenyl)ureido]butyl}piperidinium chloride.
