NaH (60%, 0.5 g, 23.6 mmol) was diluted in DMSO (50 mL) and stirred for 30 min at rt under nitrogen. Trimethylsulfoxonium iodide (7.8 g, 35.37 mmol) was added in portions at 0° C. The reaction mixture was stirred for 1 h. Then a solution of 4-benzyloxybenzaldehyde (5 g, 23.58 mmol) in THF (15 mL) was added. The reaction solution was stirred at rt for 3 h. The reaction mixture was poured into ice-water and extracted with ether. The organic layer was dried over Na2SO4 and concentrated to give 2-(4-(benzyloxy)phenyl)oxirane, which was used for the next step without further purification.
