실험 절차

To a solution of E/Z 6-Bromo-3-(3-chloro-benzylidene)-1,3-dihydro-indol-2-one (5.3 g, 16 mmol) prepared in example 157a in N,N-dimethyl-formamide (50 mL) at 0° C. was added NaH (60% in mineral oil) (0.64 g, 16 mmol), followed by the dropwise addition of 2-(trimethylsilyl)ethoxymethyl chloride (2.65 g, 16 mmol) in tetrahydrofuran (40 mL). The reaction mixture was stirred at 0° C. for 0.5 h, then poured into ice-water. The crude was extracted with ethyl acetate twice. The combined organic layer was dried over Na2SO4. The solvent was removed and the residue was purified by chromatography (hexanes) to give E/Z-6-Bromo-3-(3-chloro-benzylidene)-1-(2-trimethylsilanyl-ethoxymethyl)-1,3-dihydro-indole-2-one as a yellow oil (Yield 4.5 g, 60%).
