Procedure
The title compound, m/e=405.7 ([M−H]−), was produced in analogy with example 54, steps 1 to 6. Thus, 8-bromo-1-octanol was protected in step 1, leading to 2-(8-bromo-octyloxy)-tetrahydro-pyran, which was reacted in step 2 with 3-phenoxypropanol, affording 2-(8-(3-phenyl-propoxy)-octyloxy)-tetrahydro-pyran, which after deprotection in step 3 gave 8-(3-phenyl-propoxy)-octan-1-ol. This was oxidized in step 4 to 8-(3-phenyl-propoxy)-octanoic acid, which was coupled in step 5 with (R)-3-amino-4-dimethylamino-butyric acid benzyl ester dihydrochloride, leading to (R)-4-dimethylamino-3-[8-(3-phenyl-propoxy)-octanoylamino]-butyric acid benzyl ester, which was hydrogenated in step 6.
