Title compds. (I; Het = lower alky1, halogen, 2- or 4- imidazoly1, 2-pyridy1, 2-thiazoly1, 3-isothiazoly1, etc.; Y = s, methylene; Z = H, lower alky1; A = C1-5 alkylene) were prepd. by reaction of ii and iii(O = nitroamino, lower alky1-thio, benzylthio). Thus, 2-nitroamino-5-(6-methoxy-3-pyridy1-methy1)-4-pyrimidone and 2-(2-thiazolylmethylthio)ethylamine were refluxed for 18 hr to give 2-≮ 20(2-thiazolylmethylthio)-ethylamino≉-5-(6-methoxy-3-pyridylmethy1)-4pyrimidone(m.p.95-97oc).
