Procedure

300 g. of 2-chloro-4,6-diamino-s-triazine, 180 g. of 1,2,5,6-tetrahydropyridine and 170 g. of sodium bicarbonate are mixed in 1700 ml. of n-butanol and heated to reflux for 18 hours. The mixture is cooled and filtered. The residue is digested three times with hot chloroform and ethanol and filtered. The filtrates are combined and concentrated, there being obtained pure 2,4-diamino-6-[3,6-dihydro-1(2H)-pyridyl]-s-triazine having a melting point of 200°-202° C.
