実験手順
A solution of 2-(4-dimethylaminomethyl-2-pyridylmethylthio)ethylamine (1 g) and 2-nitroamino-5-(2-methoxy-4-pyridylmethyl)-4-pyrimidone (1.23 g) was refluxed in pyridine (6 ml) for 10 hours, concentrated in vacuo and chromatographed on silica gel column eluted with ethyl acetate-ethanol-28% W:W aqueous ammonia (by volume 10:15:2). Recrystallisation from acetonitrile:ether (1:5) gave 2-[2-(4-dimethylaminomethyl-2-pyridylmethylthio)ethylamino-5-(2-methoxy-4-pyridylmethyl)-4-pyrimidone (1.21 g) m.p. 65°-74° C.
