Using the procedure of Example A-1, step 2, a solution of 4-phenyl-3-(4-pyridyl)-3-butene-2-one (step 2) (1.25 g, 5.6 mmol) in methanol (20 ml) was treated with 30% aqueous hydrogen peroxide (1 ml) in the presence of sodium hydroxide (230 mg, 5.7 mmol). The crude product was purified by chromatography (silica gel, 1:1 ethyl acetate/hexane) to give 4-phenyl-3-(4-pyridyl)-3,4-epoxy-2-butanone (270 mg, 20%).
