2-[(Thiazol-2-yl)methylthio]ethylamine → 3-[2-(2-Thiazolylmethylthio)ethylamino]-6-(3-pyridylmethyl)-1,2,4-triazin-5-one

Participants

Reaction Steps

3-Methylthio-6-(3-pyridylmethyl)-1,2,4-triazin-5-one (3.28 g) and 2-(2-thiazolylmethylthio)ethylamine (2.7 g) were heated together on an oil bath (160°-170°) for 1 hour. The cooled mixture was triturated with isopropanol and the solid was twice recrystallised from ethanol to give the title compound as pale yellow plates (3.1 g) m.p. 158°-59°.
