Reaction Steps

2-(4-Aminobutylamino)-5-chloro-3-methylpyridine (1.81 g) and 2-nitroamino-5-(6-methylpyrid-3ylmethyl)-4-pyrimidone (1.95 g) were fused together on an oil bath at 140°-50° C. for 2 hr. On cooling the mixture was treated with water and dilute hydrochloric acid and some solid material removed at pH 4. On raising the pH to 5 a precipitate was obtained which on recrystallising twice from dimethyl formamide/water gave 2-[4-(5-chloro-3-methylpyrid-2-ylamino)butylamino]-5-(6-methylpyrid-3-ylmethyl)-4-pyrimidone (1.2 g; 39%) m.p. 202°-3° C.
