Versuchsvorschrift

To a stirred solution of {(S)-1-[(S)-1-(6-bromo-2-methoxy-naphthalen-1-ylmethyl)-2-oxo-2,3,4,5-tetrahydro-1H-benzo[b][1,4]diazepin-3-ylcarbamoyl]-ethyl}-methyl-carbamic acid tert-butyl ester (Intermediate 11) (300 mg, 0.49 mmol) in THF (10.0 mL) was added Cs2CO3 (320 mg, 0.98 mmol) and stirred at RT for 3 h. The mixture was cooled to 0° C., isophthaloyl dichloride (49 mg, 0.24 mmol) was added, the cooling bath was removed and the mixture was stirred at RT. After 18 h, the mixture was diluted with ethyl acetate, washed with water and brine. The organic layer was evaporated and the residue purified by preparative reverse phase HPLC to afford tert-butyl N-[(1S)-2-[[(3S)-5-[(6-bromo-2-methoxy-1-naphthyl)methyl]-1-[3-[(3S)-5-[(6-bromo-2-methoxy-1-naphthyl)methyl]-3-[[(2S)-2-[tert-butoxycarbonyl(methyl)amino]propanoyl]amino]-4-oxo-2,3-dihydro-1,5-benzodiazepine-1-carbonyl]benzoyl]-4-oxo-2,3-dihydro-1,5-benzodiazepin-3-yl]amino]-1-methyl-2-oxo-ethyl]-N-methyl-carbamate (18 mg, 3%). LC-MS: 1353.8 (M+H), 1370.8 (M+NH4).
