Reaction Steps

(b)(i) 2-Nitroamino-5-(3-pyridylmethyl)-4-pyrimidone (12.36 g) was added to a stirred mixture of 2-(5-furylmethylthio)ethylamine hydrochloride (10.65 g) and sodium ethoxide (prepared from 1.26 g sodium) in dry ethanol (300 ml) and the mixture was boiled under reflux for 44 hours and evaporated to dryness. The residue was triturated with water (discarded) and recrystallised from aqueous 2-propanol to give 2-[2-(2-furylmethylthio)ethylamino]-5-(3-pyridylmethyl)-4-pyrimidone, m.p. 136°-139°.
