Procedure
The title compound was synthesized by analogy with the synthesis process of Example 1 by reacting 100 mg (119 μmol) N-methyl-L-valyl-N-[(3R,4S,5S)-1-{(2S)-2-[(1R,2R)-3-{[2-(1H-indol-3-yl)ethyl]amino}-1-methoxy-2-methyl-3-oxopropyl]pyrrolidin-1-yl}-3-methoxy-5-methyl-1-oxoheptan-4-yl]-N-methyl-L-valinamide trifluoroacetic acid salt (intermediate 24) with a 15% aqueous solution of 4-oxobutanoic acid in the presence of sodium cyanoborohydride.
