Versuchsvorschrift
2-(2-Thiazolylmethylthio)ethylamine (2.00 g) and 2-nitroamino-5-(3-methoxybenzyl)-4-pyrimidone (1.58 g) were fused together at 130° for 4 hours. The mixture was triturated with hot water and the residue was recrystallised from 2-propanol to give 2-[2-(2-thiazolylmethylthio)ethylamino]-5-(3-methoxybenzyl)-4-pyrimidone (0.93 g), m.p. 122°-4°. A sample was treated with hydrogen chloride in ethanol and after recrystallision from isopropanol/methanol it had m.p. 104°-6° and gave analytical data corresponding to a hemihydrochloride.
