合成路线1
该中间体在本合成路线中的序号：(IX)Treatment of alpha-chlorophenylacetyl chloride (VIII) with methylamine provided the corresponding chloro amide (IX), which was subsequently condensed with 2-aminobenzyl alcohol (X) to afford amino alcohol (XI). Cyclization of (XI) in the presence of AlCl3 led to the dibenzoazepine (XII). This was converted to the tetracyclic compound (XIV) by reaction with dibromoethane (XIII) in the presence of Na2CO3. Reduction of the amide carbonyl group of (XIV) by means of LiAlH4 furnished the title compound. In a related strategy, amide (XII) was initially reduced to diamine (VI) by using LiAlH4. Subsequent condensation of (VI) with dibromoethane (XIII) led to the target tetracyclic derivative
