Versuchsvorschrift

To 3-(tert-butyl-dimethyl-silanyloxy)-2,6-difluoro-benzaldehyde (37, 3.50 g, 12.9 mmol) in N,N-dimethylformamide (50 mL) was added tetrabutylammonium fluoride trihydrate (4.40 g, 14.0 mmol). The reaction was stirred at room temperature for 1 hour. The reaction mixture was poured into water and extracted with ethyl acetate. The organic layer was washed with brine, dried over anhydrous sodium sulfate and concentrated to give crude compound 38 that was used in the next step.
