実験手順

In a manner analogous to that of Example 2, 26.2 g (0.2 mole) of dimethylmaleic acid anhydride and 32.6 g (0.2 mole) of 3,4-dichloroaniline are condensed to give N-(3,4-dichlorophenyl)-dimethyl-maleimide, which is then dissolved in 300 ml of methanol. To this solution is slowly added in portions, with stirring, 10.8 g of sodium borohydride. After the addition is complete and the generation of gas has subsided, the reaction mixture is poured into ice water. The white precipitate is filtered off, washed with methanol and dried. There is obtained 49.3 g (84% of theory) of the above product in the form of colourless crystalline powder, m.p. 188°.
