反応条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

実験手順: 2,6-Dichloro-4-(2-methoxyethoxy)benzaldehyde (0.5 g, 2.0 mmol) in acetone (20 mL) were cooled down in ice bath and then potassium permanganate (0.47 g, 3.0 mmol) in water (5 mL) was added slowly under vigorous stirring. The reaction mixture was warmed up slowly to room temperature and reacted over 24 h. The reaction mixture was filtered through celite and washed with acetone. The organic phase was evaporated and then re-dissolved in EtOAc to be extracted with 1N HCl aqueous solution. The organic phase was dried over magnesium sulfate, filtered and concentrated in vacuum to afford the compound 2,6-dichloro-4-(2-methoxyethoxy)benzoic acid. reacted over 24 h The reaction mixture was filtered through celite washed with acetone The organic phase was evaporated re-dissolved in EtOAc to be extracted with 1N HCl aqueous solution The organic phase was dried over magnesium sulfate filtered concentrated in vacuum

反応条件: temp:100.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

実験手順: 2,6-Dichloro-4-hydroxybenzaldehyde (0.5 g, 2.62 mmol), 1-bromo-2-methoxyethone (0.3 mL), sodium iodide (0.4 g, 0.4 mmol) and potassium carbonate (0.9 g, 6.55 mmol) were added in DMF (5 mL) and heated at 100° C. for 1 h under stirring. When the reaction was done, the reaction mixture was diluted with EtOAc and extracted three times with water. The organic phase was dried over magnesium sulfate, filtered and concentrated in vacuum. The resulting solid was purified by normal phase chromatography (hexanes:EtOAc 3:1) to afford 2,6-dichloro-4-(2-methoxyethoxy)benzaldehyde. extracted three times with water The organic phase was dried over magnesium sulfate filtered concentrated in vacuum The resulting solid was purified by normal phase chromatography (hexanes:EtOAc 3:1)
