Procedure
2-(3-Aminopropylamino)-5-chloro-3-methylpyridine (0.92 g) and 2-methylthio-5-(4-pyridylmethyl)-4-pyrimidone (0.90 g) were heated together under reflux in pyridine (5 ml) for 46 hr. After stripping to dryness the residue was triturated with wet ether to give a white solid. Repeated recrystallisation from isopropanol/water gave 2-[3-(5-chloro-3-methylpyrid-2-ylamino)propylamino]-5-(4-pyridylmethyl)-4-pyrimidone (0.95 g; 64%) m.p. 90°-92° C.
