Versuchsvorschrift

Acetic anhydride (30 mL) was added to 2,4-dimethyl-pyridine 1-oxide (1.93 g, 15.7 mmol) described in Manufacturing Example 11-1-1, and the mixture was stirred for 10 minutes at 110° C. The reaction solution was allowed to room temperature and concentrated under a reduced pressure. The resulting residue was purified by silica gel column chromatography (heptane:ethyl acetate=1:2, then ethyl acetate) to obtain the title compound (774 mg, 29.8%).
