Reaction Steps

Successive reaction of 3-bromo-4-methoxy-N,N-dimethylbenzylamine with magnesium and formaldehyde (in a similar manner to Example 7) gave 5-dimethylaminomethyl-2-methoxybenzyl alcohol, m.p. 67°-69°, which was heated under reflux for 4 hours with cysteamine hydrochloride in acetic acid to give, after basification and chloroform extraction, 2-(5-dimethylaminomethyl-2-methoxybenzylthio)ethylamine, as an oil. This oil was heated under reflux with 1.1 molar equivalents of 2-nitroamino-5-(3-pyridylmethyl)-4-pyrimidone in ethanol for 28 hours to give 2-[2-(5-dimethylaminomethyl-2-methoxybenzylthio)-ethylamino]-5-(3-pyridylmethyl)-4-pyrimidone which was treated with hydrogen chloride in ethanol and purified as the trihydrochloride salt m.p. 232°-235° (recrystallised from methanol-ethanol).
