Reaktionsschritte
2,6-Dibromophenol (14.5 g, 0.058 mole) was treated with sodium methoxide (from 10.3 g sodium, 0.45 g atom) in methanol (100 ml) and dimethylformamide (100 ml) in the presence of cuprous iodide (2 g) in the same way as described in detail for 2,6-dibromo-4-t-butylphenol in Example 9. The crude yield of title product was 5.4 g (60%), m.p. 53°-6° C. (literature gives 55°-6° C.). The lower yield may be explained by incomplete extraction, 2,6-dimethoxyphenol being to some extent water soluble.
