该中间体在本合成路线中的序号：(III)The electrochemical oxidation of 3,4-dihydroxy-2-methoxybenzophenone (I) in the presence of (1-aminocyclopentyl)methanol (II) using tetraethylammonium perchlorate as the supporting electrolyte led to the formation of a transient ortho-quinone (III), which, by intramolecular ring closure with amino alcohol (II), gave rise to the benzoxazinone (IV). Subsequent condensation of (IV) with benzylamine (V) produced the Schiff base (VI). This was finally converted to the title compound by electrochemical reduction.
