To 20.3 g of 4-propoxy-2,3-dimethylpyridine-1-oxide, 44.0 g (4.0 eq.) of acetic anhydride was added, and the mixture was allowed to react for 4 hours at 90° C. Acetic anhydride was distilled off, and then the resulting concentrated residue was purified on a silica gel column, to obtain 27.8 g of 2-acetoxymethyl-3-methyl-4-propoxy-pyridine as an oily matter.
