4-Hydroxybenzaldehyde → p-(4'-n-Butylbenzoyloxy)benzaldehyde

Participants

Reaction Steps

4-n-Butylbenzoyl chloride (39, 2 g, 0.2 m) was added dropwise to a solution of 4-hydroxybenzaldehyde (24.4 g), (0.2 m) anhydrous benzene (320 ml) and dry pyridine (30 ml) with stirring. After completion of addition stirring was continued for 24 hours at room temperature. The resulting reaction mixture was poured into cold water. The organic layer was separated and washed with diluted hydrochloric acid solution, diluted potassium hydroxide solution and water, then dried over anhydrous sodium sulfate. The solvent was evaporated and the residue was crystallized from ethanol to yield p-(4'-n-butylbenzoyloxy)benzaldehyde (26.3 g, 46%) mp 49.7° C.
