4-Hydroxybenzaldehyde → 4-(2-Morpholinoethoxy)benzaldehyde

Participants

Reaction Steps

92.8 g of 4-hydroxybenzaldehyde are dissolved in 820 ml of dimethylformamide. After the addition of 228 g of 4-(2-choroethyl)morpholine and 415 g of finely powdered potassium carbonate the reaction mixture is heated to 100° overnight under argon and while stirring vigorously. The cooled solution is poured into 3 l of ice-water, extracted with ethyl acetate, washed with water, dried and evaporated. The residual dark oil is distilled in a high vacuum and gives 132 g of 4-(2-morpholinoethoxy)benzaldehyde as a yellowish oil, boiling point 145°-150°/33 Pa.
