Water → (2-Benzyloxyphenyl)-(4-chlorophenyl)methanol

참여 물질

반응 단계

In a nitrogen stream, an n-butyllithium hexane solution (2.44 M, 10.3 mL) was added dropwise to a solution of 1-benzyloxy-2-bromobenzene (6.0 g, 22.8 mmol) in THF (228 mL) at −78° C. and the mixture was stirred at the same temperature for 30 minutes. To this solution, a solution of 4-chlorobenzaldehyde (2.67 g, 19.0 mmol) in THF (76 mL) was added dropwise at −78° C. The reaction mixture was stirred at the same temperature for two hour and further more at 0° C. for one hour. Water was added thereto and the mixture was extracted with ethyl acetate. The organic layer was washed with a saturated sodium chloride aqueous solution and dried (anhydrous magnesium sulfate), and then the solvent was distilled under reduced pressure. The obtained residue was purified by silica gel column chromatography [developing solution=ethyl acetate: n-hexane (1:5)] to obtain the title compound (4.76 g, 77%).
