The reaction of benzamidine with aromatic aldehydes gives 2-aryl-4, 6-diphenyl-1, 2-dihydro-sym-triazines. These compounds react as heterodienes with acetylenedicarboxylic ester. In this process, the triazine ring is cleaved with the splitting out of the imine of an aromatic aldehyde, and the ester of 2,4-diphenyl-5,6-pyrimidinedicarboxylic is formed.
