To a solution of (E)-methyl 3-(4-cyclohexylphenyl)acrylate (200 mg, 0.82 mmol) in DMSO (20 mL) was added freshly prepared Corey's reagent (92 mg, 0.98 mmol) at RT and stirred for 3 h. The reaction was quenched with cold water and then extracted with EtOAc (2×20 mL). The combined organic layers were dried over magnesium sulfate, filtered and then concentrated in vacuo to obtain crude product. The crude material was purified via silica gel column chromatography eluting with 5% EtOAc/95% hexanes to afford methyl 2-(4-cyclohexylphenyl)cyclopropanecarboxylate (150 mg, 47%) as a solid.
