Reaction Conditions

Reaction Steps

To a solution of dimethyl methylphosphonate (0.7 mL) in THF (8.2 mL) was added 2.44 M n-butyllithium/n-hexane solution (2.6 mL) at −78° C., and the reaction mixture was stirred for 0.5 hr at −78° C. A solution of [2-benzyloxy-5-(4-ethylbenzyl)benzyl chloride (1.50 g) in THF (8.2 mL) was added to the mixture at −78° C., and the reaction mixture was stirred for 2 hr at −78° C.˜−10° C. The reaction was quenched by the addition of saturated aqueous ammonium chloride and extracted with ethyl acetate. The combined ethyl acetate extracts were washed with brine, dried over anhydrous sodium sulfate and evaporated. The residue was purified by silica gel column chromatography (ethyl acetate/n-hexane=2/3) to give the title compound (0.74 g) as a colorless oil.
