Reaction Steps

tert-butyl (1E,4E)-8-bromo-4-((3-(tert-butyldimethylsilyloxy)propyl)(propyl)carbamoyl)-3H-benzo[b]azepin-2-ylcarbamate, isobutyl 2-(2-bromophenyl)acetate (1.5 equiv), tetrakis(triphenylphosphine)palladium(0), 2M aqueous potassium carbonate (3 equiv) were combined in 2 mls of acetonitrile in a microwave reaction vial. This mixture was heated in a microwave to 100° C. for 30 minutes. The mixture was then diluted with EtOAc, washed twice with brine, dried over sodium sulfate, and concentrated under reduced pressure. Preparative thin layer chromatography (2×0.5 mm plates, 7% MeOH/DCM) afforded isobutyl 2-(4-((1E,4E)-2-(tert-butoxycarbonylamino)-4-((3-(tert-butyldimethylsilyloxy)propyl)(propyl)carbamoyl)-3H-benzo[b]azepin-8-yl)phenyl)acetate.
