Reaktionsbedingungen

Temperatur: 100 °C

Versuchsvorschrift

26 mg (26 μmol) of N-methyl-L-valyl-N-[(3R,4S,5S)-1-{(2S)-2-[(1R,2R)-3-{[(2S)-1-(adamantane-1-ylmethoxy)-1-oxo-3-phenylpropane-2-yl]amino}-1-methoxy-2-methyl-3-oxopropyl]pyrrolidin-1-yl}-3-methoxy-5-methyl-1-oxoheptan-4-yl]-N-methyl-L-valinamide sodium trifluoroacetate (intermediate 29) and 33.9 μl of 15% aqueous amber aldehyde acid solution (53 μmol) were dissolved in 957 μl of a 1:1-dioxane/water composition and heated for 1 hour at a temperature of 100° C. After a short cooling period 1.81 mg (29 μmol) of sodium cyanoborohydride were added. The reaction composition was formulated with 0.1 of N hydrochloric acid to pH 3 and heated for 2 hours at a temperature of 100° C. It was reheated again for 2 hours at 100° C. after the same amounts of amber aldehyde acid solution, sodium cyanoborohydride, and hydrochloric acid had been added once again. Afterwards, the reaction composition had been separated directly by means of preparative HPLC. The yield was 18.5 mg (73% o. th.) of the title compound.
