2-[(Thiazol-2-yl)methylthio]ethylamine → 2-[2-(2-Thiazolylmethylthio)ethylamino]-5-(4-pyridylmethyl)-4-pyrimidone

Participants

Reaction Steps

An intimate mixture of 5-(4-pyridylmethyl)-2-methylthio-4-pyrimidone (1.55 g) and 2-(2-thiazolylmethylthio)ethylamine (1.16 g) was heated at 135°-140° with frequent stirring. After cooling, the reaction mixture was triturated under water to give 2-[2-(2-thiazolylmethylthio)ethylamino]-5-(4-pyridylmethyl)-4-pyrimidone. This product was acidified with dilute ethanolic hydrogen chloride, evaporated to dryness and the residue recrystallised from methanol to give the title compound m.p. 190°-195°.
