실험 절차
4-Methyl -5-oxazolecarbaldehyde (600 m g) in dry tetrahydrofuran (10 ml) was added dropwise to a stirred solution of phenyllithium (2.0M solution in cyclohexane and diethyl ether, 2.8 ml) in tetrahydrofuran (20 ml) at -70° C. under an atmosphere of dry nitrogen. After 1 hour the mixture was allowed to warm to room temperature. After a further 1 hour saturated aqueous sodium hydrogen carbonate was added and the mixture was extracted with ethyl acetate. The product was purified by flash chromatography to yield the title compound.
