Procedure

A mixture of 3.05 g (16.5 mmole) of 6-aminomethyl-4-methoxy-2-methylthiopyrimidine (from Example 4) and 50 ml of glacial acetic acid was heated at reflux for 16 hours, and was then evaporated. The residue obtained was dissolved in 20 ml of five percent aqueous sodium hydroxide solution and extracted with four 30 ml portions of chloroform. The combined extracts were washed twice with 30 ml portions of water and then with 30 ml of saturated aqueous sodium chloride solution. The combined extracts were then dried over magnesium sulfate and evaporated to provide 6-acetylaminomethyl-4-methoxy-2-methylthiopyrimidine as an off-white solid. The structural assignment was confirmed by infrared and nuclear magnetic resonance spectral analyses.
