Reaction of 2-(3-bromo-2-pyridylmethylthio)ethylamine with 1.15 molar equivalents of 2-nitroamino-5-(2-methoxy-4-pyridylmethyl)-4-pyrimidone in refluxing ethanol for 18 hours gave 2-[2-(3-bromo-2-pyridylmethylthio)ethylamino]-5-(2-methoxy-4-pyridylmethyl)-4-pyrimidone m.p. 70-72° which was boiled under reflux in ethanol containing hydrogen chloride to give 2-[2-(3-bromo-2-pyridylmethylthio) ethylamino]-5-(2-hydroxy-4-pyridylmethyl)-4-pyrimidone trihydrochloride, m.p. 195-198.5°.
