실험 절차

The title compound, m/e=432.5 ([M+H]+), was produced in analogy with example 1, steps 1 to 4. Thus, 1,8-octanediol was alkylated in step 1 with 2,3,4-trifluorobenzyl bromide, leading to 8-(2,3,4-trifluoro-benzyloxy)-octan-1-ol, which was oxidized in step 2 to 8-(2,3,4-trifluoro-benzyloxy)-octanoic acid. This was coupled in step 3 with (R)-3-amino-4-dimethylamino-butyric acid benzyl ester dihydrochloride to produce (R)-3-[8-(2,3,4-trifluoro-benzyloxy)-octanoylamino]-4-dimethylamino-butyric acid benzyl ester, which was hydrogenated in step 4.
