at room temperature results in the displacement of an aromatichydrogen at the 4-position by methoxide, affording 2,4-dinitroanisole and its 6-substituted derivatives, respectively, in low to moderate yield. In contrast, an equimolar reaction under similar conditions leads to the replacement of the nitro group in preference to the ringhydrogen. The reaction does not take place with lithium methoxide
