合成路线1
该中间体在本合成路线中的序号：(VIII)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.
