実験手順

A 6.0 g quantity of 4,4′-dihydroxydiphenylmethane is dissolved in a solution of 12.6 ml of triethylamine in 50 ml of 1,2-dichloroethane in a 250 ml flask. To the solution is slowly added a solution of 15.5 g of methyl maleimidobenzoyl chloride in 50 ml of 1,2-dichloroethane. The mixture is allowed to react at room temperature for 16 hr. The reaction mixture is precipitated in water, filtered under reduced pressure, washed sequentially with water and ethanol, and dried at 60° C. under vacuum for 48 hr, yielding the bismaleimide compound of Formula 20m.
