DEAD (256 mg, 1.47 mmol), phenol 34 (194 mg, 1.28 mmol), alcohol 26j (200 mg, 1.28 mmol), and TPP (386 mg, 1.47 mmol) in 13 ml anhydrous ether were reacted according to the procedure for compound 35a. The crude product was purified via flash chromatography over silica gel with gradual elutions from 95/5 to 90/10 (v/v, Hex/EtOAc). Evaporation of the solvent yielded 266 mg (72%) of colorless liquid.
