Versuchsvorschrift

(S)-3-(4′-cyano-biphenyl-4-yl)-2-{[(3R,7S)-3-(4-hydroxy-phenyl)-1-methyl-2-oxo-6-((R)-1-phenyl-propyl)-2,3,5,6,7,8-hexahydro-1H-4-oxa-1,6-diaza-anthracene-7-carbonyl]-amino}-propionic acid methyl ester (52 mg) was dissolved in 1 mL of DMF To this solution was added 3,4-dichlorobenzyl bromide (33 mg) and potassium carbonate. The mixture was stirred at room temperature for 6 hours and was poured onto ethyl acetate and saturated sodium bicarbonate. The organic layer was dried over sodium sulfate and concentrated. The residue was purified over silica (hexanes-ethyl acetate-MeOH, 6-4-0.1) to provide (S)-3-(4′-cyano-biphenyl-4-yl)-2-{[(3R,7S)-3-[4-(3,4-dichloro-benzyloxy)-phenyl]-1-methyl-2-oxo-6-((R)-1-phenyl-propyl)-2,3,5,6,7,8-hexahydro-1H-4-oxa-1,6-diaza-anthracene-7-carbonyl]-amino}-propionic acid methyl ester (16 mg).
