Dichloromethane → 4-Dodecyloxybenzyl alcohol

참여 물질

반응 단계

To a 0° C. slurry of LAH (13.0 g, 343 mmol) in dry THF (400 mL) was added slowly methyl 4-dodecyloxybenzoate (100 g, 312 mmol) in dry THF (350 mL) over 1.5 hours. Upon addition, the mixture was stirred at room temperature for one hour, after which TLC (CH2Cl2) showed completion. Reaction was cooled to 0° C. and quenched by successive addition of H2O (13 mL), 15% NaOH (13 mL), and H2O (39 mL), and stirring continued until H2 evolution ceased. Reaction mixture was then filtered and the lithium salts rinsed generously with CH2Cl2. The filtrate was dried over MgSO4 and concentrated to give the title benzyl alcohol (80 g, 88%), which was taken to the next step without further purification.
