Procedure

To a stirred solution of 3-phenyl-4-(4-pyridyl)-3-butene-2-one (step 1) (500 mg, 2.24 mmol) in methanol (10 ml) at room temperature was added an aqueous solution (9 ml) of sodium hydroxide (100 mg, 2.24 mmol) and hydrogen peroxide (0.5 ml of 30% aqueous solution, 4.4 mmol). After stirring for 2 hours, sodium chloride was added and the reaction was extracted with ethyl acetate. The combined organic layers were dried over magnesium sulfate, filtered, and concentrated in vacuo to provide the crude 3-phenyl-4-(4-pyridyl)-3,4-epoxy-2-butanone (385 mg, 65%) as an oil. This was used in the next step without further purification.
