反応手順

To a mixture of 27.8 g (0.1 mole) of 4-(decyloxy)benzoic acid in 500 ml of tetrahydrofuran cooled to 0° C is slowly added 16.2 g (0.1 mole) of N,N'-carbonyldiimidazole. The mixture is heated to reflux for 1 hour then cooled to -20° C. To the cooled mixture is added 1.9 g (0.05 mole) of lithium aluminum hydride and stirring is continued at -20° C for 1 hour. To the reaction mixture is slowly added 100 ml of 5% aqueous hydrochloric acid followed by the addition of ether. The ether layer is separated and washed with 5% aqueous hydrochloric acid, water, and 5% aqueous sodium bicarbonate then dried over sodium sulfate, filtered and evaporated to dryness to give 4-(decyloxy)benzaldehyde.
