1-(2,2-Diethoxyethoxy)-4-methoxybenzene → Acetaldehyde, (4-methoxyphenoxy)-

Participants

Reaction Steps

1-(2,2-Diethoxyethoxy)-4-methoxybenzene (4.8 g, 20 mmol) was dissolved in 1% aqueous HCl (30 mL) and acetone (15 mL). The reaction mixture was heated under refluxed for 2 h. Acetone was removed under reduced pressure. The aqueous mixture was neutralized with saturated sodium bicarbonate, and extracted with ethyl acetate. The organic layer was dried over sodium sulfate, filtered, and concentrated. The residue was dried under reduced pressure to afford the desired product which was used in the next step without further purification. (3.30 g, 99.3%).
