合成路线1
该中间体在本合成路线中的序号:(III)The reductocondensation of tetrahydropyran-4-one (I) with methylamine (II) by means of H2 over Pd/C in methanol gives 4-(methylamino)tetrahydropyran (III), which is then alkylated with 4-nitrobenzyl bromide (IV) and K2CO3 in DMF to yield the tertiary amine (V). Finally, the nitro group of (V) is educed with SnCl2 and conc. aq. HCl to afford N-(4-aminobenzyl)-N-methyl-N-(tetrahydropyran-4-yl)amine, the target intermediate (VI).
