Abstract

Diaminopyrimidines, which may be substituted by further monovalent radicles, other than 2 : 4-diaminopyrimidines, are condensed with aldehyde or compounds splitting off aldehydes such as formaldehyde. In examples (1) 2 - mercapto - 4 - 6 - diamino-, 2-hydroxy-4-6-diamino-, (2) 2-methylthio-4-6-diamino-, (3) 2-cyanamino-4-6-diamino-, (4) 2-6-dihydroxy-4-5-diamino-, (5) 2-phenyl-4-6-diamino-pyrimidines are condensed with formaldehyde. Reference has been directed by the Comptroller to Specification 455,008.
