合成路线1
该中间体在本合成路线中的序号：(XIV)The condensation of 2,4,6-trimethylaniline (I) with adipoin (II) in hot toluene, followed by reaction of the resulting intermediate (III) with malononitrile (IV), gave rise to the tetrahydroindole (V). Subsequent condensation of amino nitrile (V) with 2-methoxypropene (VI) produced the tetrahydropyrido[2,3-b]indole system (VII), which was dehydrogenated to (VIII) by means of Pd/C in boiling decalin. Acylation of (VIII) with isobutyryl chloride (IX) afforded amide (X), which was reduced to amine (XI) employing borane-dimethyl sulfide complex. Further acylation with chloroacetyl chloride (XII), and then reduction of the resulting chloroacetamide (XIII) with borane-dimethyl sulfide, provided the chloroethyl amine (XIV). This was finally treated with dimethylamine in hot N-methylpyrrolidinone in a steel bomb to furnish the desired dimethylamino compound.
