4-(5-Bromo-3-methyl-2-pyridinyl)butylamine → 2-[4-(5-Bromo-3-methylpyrid-2-yl)butylamino]-5-(4-fluorobenzyl)-4-pyrimidone

Participants

Reaction Steps

5-Bromo-2-(4-aminobutyl)-3-methylpyridine, (0.88 g) and 5-(4-fluorobenzyl)-2-methylthio-4-pyrimidone (0.75 g) were refluxed in pyridine (3 ml) for 24 hours. The pyridine was removed in vacuo and the residue triturated with ethanol (5 ml) giving a colourless solid. The solid was recrystallised from methanol giving 2-[4-(5-bromo-3-methylpyrid-2-yl)butylamino]-5-(4-fluorobenzyl)-4-pyrimidone (0.96 g) m.p. 172°-3° C.
