An intimate mixture of 5-(4-chorobenzyl)-2-methylthio-4-pyrimidone (1.36 g) and 2-(2-thiazolylmethylthio)ethylamine (0.9 g) was heated at 130°-135° for 31/2 hours. After cooling the reaction mixture was treated with 2N hydrochloric acid. Evaporation to dryness followed by recrystallisation from isopropanol/methanol gave 2-[2-(2-thiazolyl-methylthio)ethylamino[-5-(4-chlorobenzyl)-4-pyrimidone monohydrochloride, m.p. 172.5°-174.5°.
