2-[N-(3-aminopropyl)-N-methylamino]pyridine (0.74 g) and 2-methylthio-5-(3-chlorobenzyl)pyrimid-4-one (0.8 g) were heated together under reflux in pyridine (2.5 ml) for 26 hr. After stripping, the residue was recrystallised three times from ethanol/water to give 2-[3-(N-methyl-N-pyrid-2-ylamino) propylamino]-5-(3-chlorobenzyl)pyrimid-4-one 1H2O, 0.7 g (58%) mp 105°-7° C.
