4-Hydroxybenzaldehyde → 4-(2-(Diethylamino)-Ethoxy)-Benzaldehyde

Participants

Reaction Steps

To the solution of 18.4 g (0.15 mol) of 4-hydroxybenzaldehyde in 100 ml acetone, 27.5 g (0.16 mol) of N,N-diethyl-N-(2-chlorethyl)-amine IX and 22.1 g (0.16 mol) potassium carbonate was added at the room temperature under stirring. The mixture was then intensively stirred at the boiling temperature for 12 hours. The mixture was cooled, potassium chloride was separated, washed with acetone. The solvent was distilled off from the solution on the vacuum rotatory evaporator. Afforded 20 g (60.6%) of 4-diethylaminoethoxybenzaldehyde X. Colourless fluid boiling point 120-123° C./0.5 torr, n20D=1.536. Lit. [5] reports boiling point 123-125° C./0.8 torr, n20D=1.530.
