実験手順
To a solution of Pd((R)-binap)(OH2)2(OTf)2 (26.6 mg, 0.025 mmol) in toluene (3 ml) were added 3-crotonoyl-1,3-oxazolidin-2-one (155 mg, 1.0 mmol) and anisidine (148 mg, 1.2 mmol). After the resulting mixture was stirred at room temperature for 3 hours, the reaction solution was concentrated and purified by a silica gel column chromatography (hexane:ethyl acetate=4:1) to give the objective 3-[3-(4-methoxyphenylamino)butyryl]-1,3-oxazolidin-2-one (228 mg, 82% yield).
