Reaction Steps

Gantacurium, an asymmetrical chlorofumarate, was prepared in four chemical transformations from compound (XIIIB) using minor modifications of previously reported chemistry, see WO2005/041960. Isoquinolylalkanol compound (XIIIB) was condensed with trans-2,3-dichlorosuccinic anhydride and triethylamine in acetonitrile solvent to provide a monoester of chlorofumaric acid, which was then condensed with isoquinolylalkanol compound (XIIIC):
