反応条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

実験手順: To a solution of 4-hydroxybenzaldehyde (732 mg, 6 mmol) in anhydrous DMF (13 ml), under nitrogen atmosphere, K2CO3 (1658 mg, 12 mmol), and, after 10 minutes, iododecane (1785 mg, 7.2 mmol) were added. The mixture was heated to reflux for 3 hours, then water was added and the product was extracted with CH2Cl2. The organic layers were washed with water and with NaCl saturated solution, dried with Na2SO4. After evaporation of the solvent, the crude product was purified by chromatography on silica gel (Petroleum ether/Ethyl acetate 11/1) and 1530 mg (yield 97%) of the pure product of the title were obtained. The mixture was heated to reflux for 3 hours the product was extracted with CH2Cl2 The organic layers were washed with water and with NaCl saturated solution dried with Na2SO4 After evaporation of the solvent

実験手順: 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. The mixture is heated to reflux for 1 hour then cooled to -20° C The ether layer is separated washed with 5% aqueous hydrochloric acid, water, and 5% aqueous sodium bicarbonate then dried over sodium sulfate filtered evaporated to dryness
