Versuchsvorschrift

To a toluene solution of 1-(5-fluoro-2-methylphenyl)-3-trimethylsilyoxy-2-aza-1,3-butadiene in toluene (2 M, 5 mL, 10 mmol) was added E/Z 6-chloro-3-[5-chloro-2-(1-methoxycarbonyl-cyclobutoxy)-benzylidene]-2-oxo-2,3-dihydro-indole-1-carboxylic acid tert-butyl ester (1.5 g, 2.9 mmol). The reaction mixture was heated at 80° C. overnight under argon protection, then TFA (5 mL) was added, and the resulting mixture was stirred at room temperature for 20 min, evaporated in vacuo. The residue was partitioned between ethyl acetate and NaOH aq. (1 M). The organic layer was washed with water, dried over anhydrous Na2SO4, concentrated and purified by column chromatography to give the title compound as a white solid (340 mg).
