Synthesis of N-cyano-N-alkoxycarbonylalkylamino-symm-triazines and their solvolysis

The action of potassium salts of cyanoamino-symm-triazines on esters of chloroacetic and bromomalonic acids gave carbonylalkylamino-symm-triazines. The solvolysis of these esters proceeds with heterocyclilzation, leading to the formation of hydantoin derivatives.
