Procedure:
6-Cyano-3,4-epoxy-3,4-dihydro-2,2-dimethyl-2H-1-benzopyran (5.0 g) and 4.0 g of acetohydrazide were dissolved in 20 ml of ethanol and the solution was heated under reflux for 9 hours. After the reaction, the ethanol was distilled off under reduced pressure and the residue was crushed by adding ice water and filtered to obtain crystals. The crystals were dried and recrystallized from ethyl acetate-ethanol (7:1) to give 5.3 g of trans-4-(2-acetylhydrazino)-6-cyano-3,4-dihydro-2,2-dimethyl-2H-1-benzopyran-3-ol as white crystals, m.p. 209°-210° C.

Procedure:
In the same reactor used in Example 2A, there were placed 26.5 g (0.27 mole) of maleic anhydride, 0.7 g of phosphoric acid and 150 ml of mixed xylene. A solution was then added dropwise thereto under reflux of xylene, the solution having been prepared by thermally dissolving 52.8 g (0.1 mole) of 1,4-bis[4(4-aminophenoxy),α,α-dimethylbenzyl)benzene obtained in Example 1A in a mixture of 100 ml of mixed xylene and 50 ml of N,N-dimethylformamide. A dropping time of 5 hours and an aging time of 2 hours were used in order to carry out the reaction. The reaction solution was concentrated to about 1/2 the original amount and then cooled. When a temperature of 80° C. had been reached; 50 g of water was added thereto. Afterward, the solution was slowly cooled with stirring, so that crystals were precipitated. The crystals were then cooled to room temperature, filtered, and washed with cold methanol. 66.5 g of desired crude 1,4-bis[4-(4-maleimidophenoxy)-α, α-dimethylbenzyl]benzene was obtained. Its yield was 96.7%, and its purity according to HLC was 97.5%.
