4-(5-Bromo-3-methyl-2-pyridinyl)butylamine → HCID 20269068, compound

Participants

Reaction Steps

5-Bromo-2-(4-aminobutyl)-3-methylpyridine, (0.88 g) and 5-benzyl-2-nitroamino-4-pyrimidone (0.74 g) were refluxed in pyridine (3 ml) for 4 hours. The solvent was removed in vacuo and the residual oil partitioned between chloroform and water at pH 5. The chloroform extracts were dried over magnesium sulphate and evaporated to an oil. Recrystallisation from ethanol/ethyl acetate gave 2-[4-(5-bromo-3-methylpyrid-2-yl)butylamino]-5-benzyl-4-pyrimidone (0.65 g) m.p. 138°-9° C.
