Procedure

To a solution of 2.55 g. of dimethyl-5-hydroxy-2-nitroisophthalate (prepared as in Example 15, Part B) in 25 ml. of acetone is added 0.69 g. of anhydrous potassium carbonate, followed by 1.95 g. of tert-butylbromoacetate. The mixture is stirred and refluxed for 20 hr. After this time, the cooled reaction mixture is poured with rapid stirring into 200 ml. of ice-cold 1% hydrochloric acid. The solid is collected and washed well with water. Yield 3.4 g.; m.p. 106°-108° C.
