Abstract
The condensation of 2-chloro-4,6-dimethoxy- and 2,4-dichloro-6-methoxy-s-triazines with sodium derivatives of ethyl esters of acetoacetic and cyanoacetic acids and malonodinitrile was investigated. 2-Dicyanomethylene-4,6-dimethoxy-1,2-dihydro-, 2-carbethoxycyanomethylene-4,6-dimethoxy-1,2-dihydro-, and 2,4-bis(carbethoxy-methylene)-6-methoxy-1,2,3,4-tetrahydro-s-triazines were obtained in high yields.
