Ethyl Acetate → Tert-butyl 5-formylpyrazine-2-carboxylate

참여 물질

반응 단계

Sodium periodate (1.67 g) was added to a solution of t-butyl 5-((E)-2-dimethylamino-vinyl)-pyrazine-2-carboxylate (645 mg) in 50% tetrahydrofuran-water (26 mL), and the mixture was stirred at room temperature for four hours. A saturated sodium bicarbonate solution and ethyl acetate were added to the reaction solution, and the organic layer was separated. The organic layer was washed with a saturated sodium chloride solution and dried over anhydrous magnesium sulfate. The insoluble matter was separated by filtration and the filtrate was concentrated. The residue was purified by silica gel column chromatography to obtain the title compound (249 mg).
