Procedure
A mixture of ethyl 2-acetylhexanoate (5.59 g, 30 mmol), guanidine carbonate (6.49 g, 30 mmol) and ethanol (20 ml) was refluxed for 11 hours and then ice-cooled. The precipitated crystals were filtered, washed with ethanol and dried in vacuo to give 2-amino-5-butyl-6-methylpyrimidine-4-ol (2.59 g, 47%).
