Chloromethyl methyl ether (4.85 ml) was added to the reaction solution, while the solution was stirred at −40° C. The obtained mixture was stirred at room temperature for 15 hours. Water was added to the reaction solution, and the mixture was extracted with dichloromethane. The obtained organic layer was dried over magnesium sulfate and then concentrated under reduced pressure. The obtained residue was purified by silica gel column chromatography (n-heptane:ethyl acetate=19:1 to 0:1), so as to obtain the title compound (10.6 g) and 5-iodo-4-(methoxymethoxy)-2,6-dimethylpyrimidine (2.55 g).
