合成路线1
该中间体在本合成路线中的序号：(III)A new synthesis of tenidap has been developed: The reaction of 5-chloroindolin-2-one (I) with phenyl chloroformate and Et3N in THF gives 5-chloro-2-(phenoxycarbonyloxy)indole-1-carboxylic acid phenyl ester (II), which is treated with ammonium carbonate in DMF at 5 C yielding 5-chloro-2-oxoindoline-1-carboxylic acid phenyl ester (III). Compound (III) is acylated with 2-thienylcarbonyl chloride (IV) and DMAP in DMF and then acidified with conc. HCl affording 5-chloro-3-[1-hydroxy-1-(2-thienyl)methylene]-2-oxoindoline-1-carboxylic acid phenyl ester (V), which is finally treated with ammonium carbonate in DMF at 75-80 C for 5 h and acidified with conc. HCl.
