実験手順
3,4,5-Trihydroxybenzaldehyde (628 mg, 3.6 mmol) was dissolved in dimethylformamide (30 mL), and potassium carbonate (2.0 g, 14 mmol) was added thereto, followed by stirring at room temperature for 30 minutes. Next, chloromethyl methyl ether (0.96 mL, 13 mmol) was added thereto, followed by stirring at room temperature for 2 hours. After the conventional post-treatment, the residue was purified by preparative thin layer chromatography (developed with chloroform/methanol=98/2) to give 3-hydroxy-4,5-bis(methoxymethoxy)benzaldehyde (140 mg, yield 17%).
