반응 단계

In Table 2, compounds which were prepared by reacting the appropriate acids with ((S)-6-{[(4-methoxybenzyl)(tetrahydropyran-4-ylmethyl)amino]methyl}-1,2,3,4-tetrahydronaphthalen-2-yl)methylamine or, correspondingly, (S)-6-{[(4-methoxybenzyl)(tetrahydropyran-4-ylmethyl)-amino]methyl}-1,2,3,4-tetrahydronaphthalen-2-ylamine according to method G and subsequent detachment of the 4-methoxybenzyl group according to method F are compiled. To prepare examples 2-06, 2-07 and 2-08, ((S)-6-{[(4-methoxybenzyl)(tetrahydropyran-4-ylmethyl)-amino]methyl}-1,2,3,4-tetrahydronaphthalen-2-yl)methylamine was reacted according to method G with 5-hydroxypyridine-2-carboxylic acid, the resulting amide was alkylated according to method D with the appropriate alkyl bromides on the phenolic hydroxyl group, and, finally, the 4-methoxybenzyl group was removed according to method F.
