2-[N-(4-aminobutyl)-N-propylamino]pyridine (1.24 g) and 2-methylthio-5-(4-fluorobenzyl)pyrimid-4-one (1.25 g) were fused together on an oil bath at 160° C. for 2.5 hr. On cooling the residue was crystallized from ethanol/water to give 2-[4-(N-propyl-N-pyrid-2-ylamino)butylamino]-5-(4-fluorobenzyl)pyrimid-4-one 1.25H2O, 0.56 g (26%) m.p. indeterminate.
