It was established that on treatment with alkali, 2,5-disubstituted 3,3,4,4-tetracyanopyrrolidines react with primary alcohols to form 5-alkoxy-2-(N-arylidenamino)-3,4-dicyanopyrroles. Depending on the ratio of the initial reagents, another reaction route is possible, leading to 6-alkoxy-4-amino-2-R-3-CH_2R-5-cyano-3H-pyrrolo[2,3-d]pyrimidines. The effect of substituents on the reaction pathways is examined.
