合成路线1
该中间体在本合成路线中的序号：(II)A new process for the preparation of oxcarbamazepine has been reported: Reaction of 1-phenyl-2,3-dihydro-1H-indol-2-one (I) with NaOH in refluxing THF gives 2-[2-(phenylamino)phenyl]acetic acid (II), which is condensed with dimethyl carbonate (III) by means of butyl lithium in the same solvent to yield 2-[2-[N-(methoxycarbonyl)-N-phenylamino]phenyl]acetic acid (IV). Cyclization of compound (IV) by means of polyphosphoric acid (PPA) at 100 C, followed by treatment of the reaction mixture with hot methanol (65 C) affords 10-methoxy-5H-dibenzo[b,f]azepine-5-carboxylic acid methyl ester (V), which is treated with NaOH in polyethyleneglycol at 100 C to provide 10-methoxy-5H-dibenzo[b,f]azepine (VI). Reaction of (VI) with sodium cyanate in acetic acid gives 10-methoxy-5H-dibenzo[b,f]azepine-5-carboxamide (VII), which is finally treated with H2SO4.
