A mixture of 2-(5-dimethylaminomethyl-2-furylmethylthio)ethylamine (2.50 g), 2-nitroamino-5-(2-methoxy-4-pyridylmethyl)-4-pyrimidone (2.77 g) and ethanol (15 ml) was boiled under reflux for 19 hours and evaporated. The residue was triturated with hot water to leave 2-[2-(5-dimethylaminomethyl-2-furylmethylthio)ethylamino]-5-(2-methoxy-4-pyridylmethyl)-4-pyrimidone. A mixture of this pyrimidone (3.04 g), 2 N hydrogen chloride in ethanol (20 ml) and ethanol (80 ml) was boiled under reflux for 48 hours and evaporated to dryness. The residue was recrystallised from methanol/ethanol to give 2-[2-(5-dimethylaminomethyl-2-furylmethylthio)ethylamino]-5-(2-hydroxy-4-pyridylmethyl)-4-pyrimidone trihydrochloride m.p. 181°-185°.
