Water → p-n-Tetradecyloxy-4-(2-methylbutoxycarbonyl)benzylideneaniline

Participants

Reaction Steps

44.3 g of said p-(2-methylbutoxycarbonyl)benzaldehyde, 32 g of p-n-tetradecyloxyaniline, and 0.1 g of p-toluenesulfonic acid were dissolved in toluene. The solution was heated under reflux, and water generated in the dehydrating condensation was removed with a Dean-Stark condenser. After the reaction solution was cooled, the organic layer was washed with water, and the solvent (toluene) was distilled off in vacuum. The solid residue was recrystallized from ethanol to obtain yellow crystals.
