合成路线1
该中间体在本合成路线中的序号：(D)The reaction of 4-hydroxy-2-methyl-indole (V) with 1-(N-benzylisopropylamino)-3-chloro-2-propanol (D) by means of NaOH in refluxing aqueous dioxane yields the corresponding benzylamine (X), which is debenzylated by catalytic hydrogenation. The reaction of 4-hydroxy-2-methyl-indole (V) with epichlorohydrin (A) and benzylamine (B) gives 4-(3-benzylamino-2-hydroxypropoxy)-2-methyl-indole (XI), which is debenzylated by hydrogenolysis to 4-(3-amino-2-hydroxypropoxy)-2-methyl-indole (XII). The condensation of (XII) with refluxing acetone (C) affords the corresponding N-isopropylidene derivative (XIII), which is finally hydrogenated with H2 over Pd/C in methanol.
