合成路线2
该中间体在本合成路线中的序号：(VII)The reaction of 2,3-dichlorosuccinic anhydride (VIII) with isoquinolinium intermediate (IV) in dichloromethane gives the dichlorosuccinc acid monoester (IX), which is dehydrochlorinated by means of TEA in dichloromethane to yield the chlorofumaric acid monoester (X). The reaction of (X) with oxalyl chloride in the same solvent affords the acyl chloride (XI), which is finally condensed with the isoquinolinium intermediate (VII) in dichloromethane to provide the target bis isoquinolinium compound.
