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), 2N 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°.
