반응 단계

2-(3-Aminopropylamino)-3,5-dichloropyridine (1.0 g) and 2-nitroamino-5-(6-methylpyrid-3-ylmethyl)-4-pyrimidone (1.04 g) were fused together on an oil bath at 140° C. for 5 hr. On cooling, water was added, the pH adjusted to 7 and the resulting solid filtered off. Chromatography (silica gel, chloroform/methanol, graded elution 50:1 to 35:1) and recrystallisation from methanol afforded 2-[3-(3,5-dichloropyrid-2-ylamino)propylamino]-5-(6-methylpyrid-3-ylmethyl)-4-pyrimidone, (0.55 g; 33%) m.p. 147°-48° C.
