合成路线1
该中间体在本合成路线中的序号：(III)The title compound has been synthesized by several procedures. Acylation of 2-benzylaniline (I) by chloroacetyl chloride (II) gave chloroacetamide (III). Subsequent cyclization of amide (III) under Vilsmeier conditions furnished the dibenzoazepine (IV). Nucleophilic substitution of the chlorine atom of (IV) by methylamine led to amine (V). The imine function of (V) was reduced with either LiAlH4 or NaBH4 to the diamine (VI), which was further converted into the fused diketopiperazine (VII) upon heating with diethyl oxalate. The amide groups of (VII) were then reduced by means of borane in THF, yielding the target tetracyclic diamine, which was finally isolated as the corresponding hydrochloride salt
