Reaction Steps

To a suspension of 102 g terephthaldehyde in 700 ml methanol 129.4 g of 2-cyanoethylhydrazine are added drop-wise within 20 minutes. The temperature increases to about 50° C., and an orange-red solution generally arises. After about 10 minutes further crystallization occurs. Stirring continues for 30 minutes and a precipitate that appears is filtered with suction. After washing with a little cold methanol the precipitate is dried under vacuum. 187 g of beige colored product are produced.
