合成路线:The target compound has been obtained by condensation of 3.3-dimethylindoline-1-carbonyl chloride (IV) with endo-8-methyl-8-azabicyclo[3.2.1]octan-3-amine (II) by means of triethylamine followed by salification with HCl.The intermediates (II) and (IV) have been obtained as follows:A) The metthylation of 3-methylindole (III) with methylmagnesium iodid / methyl iodid,followed by hydrogenation with H2/Pt in acetic acid gives 3,3-dimethylindoline (I),which is then treated with phosghene / Et3N to afford intermediate (IV).B) The reductocondensation of 8-methyl-para-bicyclo[3.2.1]octan-3-one (V) with benzylamine and H2/Pt gives the secondary benzylamine (VI),which is finally deprotected by hydrogenation over Pd/C to give intermediate (II).
