Participants

Reaction Steps

22.4 g (0.1 mol) of the disodium salt of glutaric acid bis-(N-cyanamide) and 51.85 g (0.2 mol+20% excess) of 4-nitrobenzyl bromide are reacted in 120 ml of dimethylformamide at 36°-40° C. for 1 hour and the mixture is worked up in a manner similar to that in Example 2. 44.3 g (98.4% of theory) of a yellowish crystalline crude product are obtained, and are recrystallised from 440 ml of ethyl acetate. 31.5 g (70.0% of theory) of a colourless, crystalline product of a melting point 146.2°-148.2° C. are obtained.
