Procedure

2-(3-Aminopropylamino)pyridine (1.74 g) and 2-nitroamino-5-(6-methylpyrid-3-ylmethyl)-4-pyrimidone (2.0 g) were heated together under reflux in pyridine (8 ml) for 22 hr. The mixture was stripped, the residue triturated with ether and then water (the pH of which was adjusted to 6.5 with dilute acetic acid) to give a white solid. Recrystallisation from isopropanol gave 2-[3-(pyrid-2-ylamino)propylamino]-5-(6-methylpyrid-3-ylmethyl)-4-pyrimidone, (1.87 g; 70%), m.p. 163°-165° C.
