合成路线1
该中间体在本合成路线中的序号：(VII)The synthesis of [14C]-labeled tenidap sodium has been reported: The chlorination of [14C]-2,3-dihydro-1H-indole-2,3-dione (I) with sulfuryl chloride and triethylamine in hot acetonitrile gives the 5-chloro derivative (II), which is partially reduced by treatment with hydrazine hydrate in refluxing ethanol, followed by a treatment with KOH in the same refluxing solvent, to yield 5-chloro-2,3-dihydro-1H-indol-2-one (III). The reaction of (III) with chlorosulfonyl isocyanate (IV) in refluxing dichloromethane affords 5-chloro-2-oxo-2,3-dihydro-1H-indole-1-carboxamide (V), which is condensed with 2-thienylcarbonyl chloride (VI) by means of dimethylaminopyridine (DMAP) and triethylamine (TEA) in DMF, giving tenidap (VII). Finally, this compound is treated with NaHCO3 in hot acetone.
