Versuchsvorschrift

A mixture of 4-methylpyrimidine (10 g, 106 mmol) and para-formaldehyde (3 g) was stirred in a 50 mL sealed capacity pressure vessel at 165° C. for 3.5 hours. After cooling, ether was added and the solvents evaporated to afford an oil. This was purified by silica column chromatography using a Flashmaster system, eluting with dichloromethane, then chloroform, ether, and finally ethyl acetate. The ethyl acetate fractions were evaporated to afford the title compound as an oil.
