実験手順

To a solution of 5-iodosalicylaldehyde (6.68 g, 26.9 mmol) (Aldrich) in N,N-dimethylformamide (150 mL) was added anhydrous K2CO3 (11.17 g, 80.7 mmol), and (2-bromo-ethoxy)-tert-butyl-dimethyl-silane (7.74 g, 32.3 mmol, Aldrich). The reaction mixture was heated at 65° C. for 18 h. The crude was cooled to room temperature, diluted with ethyl acetate, washed with water, brine. The organic layer was separated, dried over MgSO4, concentrated to give 2-[2-(tert-butyl-dimethyl-silanyloxy)-ethoxy]-5-iodo-benzaldehyde as a yellow oil (Yield 10 g, 100%).
