合成路线1
该中间体在本合成路线中的序号：(V)Edoxaban tosilate has been prepared by the following synthetic strategies:
1) By conjugation of the cyclohexanediamine (I) with lithium 5-methyl-4,5,6,7-tetrahydrothiazolo[5,4-c]pyridine-2-carboxylate (II) by means of EDC and HOBt in DMAc or DMF .
2) By conjugation of diamine (I) with the HCl salt of 5-methyl-4,5,6,7-tetrahydrothiazolo[5,4-c]pyridine-2-carboxylic acid (III) in the presence of EDC, HOBt and Et3N .
3) By conjugation of the thiazolopyridinecarboxylic acid (III) with the aminocyclohexanecarboxylic acid ethyl ester (IV) using EDC, HOBt and Et3N to provide diamide ester (V) , which is then hydrolyzed with NaOH in H2O/DMSO, followed by coupling of the resultant carboxylic acid with dimethylamine in the presence of EDC and HOBt in aqueous acetonitrile .
4) By conjugation of the monoacylated cyclohexanediamine (VII) with N-(5-chloro-2-pyridyl)oxamic acid lithium salt (VI) by means of EDC and HOBt in DMF .
The tosilate salt has been obtained by treatment with p-toluenesulfonic acid in EtOH or H2O/EtOH/CH2Cl2 .
