合成路线2

该中间体在本合成路线中的序号:(XII)

An alternative route was based on the formylation of (III) with dichloromethyl methyl ether (IX) in the presence of tin chloride. The resultant aldehyde ester (X) was then reduced to the already reported diol (VIII) by means of LiBH4. The crude trifluoroacetate ester obtained by treatment of diol (VIII) with trifluoroacetic anhydride was then refluxed with isopropanol to furnish the isopropyl ether (XI). The remaining hydroxyl group was finally esterified by treatment with N,N-dimethylglycine (XII) in the presence of EDC and DMAP.

该中间体在本合成路线中的序号:(IX)

The reaction of indoline (I) with formic acid in refluxing toluene gives N-formylindoline (II), which is treated with chlorosulfonic acid to yield 5-(chlorosulfonyl)indoline-1-carbaldehyde (III). The reaction of (III) with 3,4,5-trimethoxyaniline (IV) and pyridine in THF affords the sulfonamide (V), which is deformylated to sulfonamide (VI) with HCl in methanol. The reaction of indoline (VI) with salcomine and O2 in methanol provides the corresponding indole derivative (VII), which is methylated with methyl iodide and NaHMDS in THF to give 1-methyl-N-(3,4,5-trimethoxyphenyl)-1H-indole-5-sulfonamide (VIII). Finally, this compound is condensed with N,N-dimethylglycine (IX) by means of DCC and 4-(1-pyrrolidinyl)pyridine (pypyr) in dichloromethane.
