Reaktionsschritte
This compound was prepared in a manner analogous to that of Step (b) of Example 1, using 17.0 grams (0.113 mole) of 5-ethyl-2-formylphenol, 27.7 grams (0.116 mole) of 2-(1,1-dimethylethyldimethylsilyloxy)ethyl bromide, 19.2 grams (0.139 mole) of potassium carbonate, and a catalytic amount of 18-crown-6 in 200 mL of THF. The yield of the subject compound was 12.7 grams, following purification by column chromatography on silica gel. The NMR spectrum was consistent with the proposed structure.
