反応手順

Dimethyl fumarate (781 mg; 1.1 eq.) was added to 5-ethoxyoxazole (557.3 mg; 4.9 mmol), and the mixture was reacted at 120° C. for 1.5 hours. The reaction residue was purified by silica gel column chromatography (eluent: ethyl acetate/hexane 2:1), to give crude crystals of the title compound. Yield: 730 mg (70.2%). The crude crystals were recrystallized from dichloromethane-hexane, to give colorless plates.
