실험 절차

A solution of 1.1 g (5.4 mmol) of 5-(4-nitrophenyl)-1,3-oxazol-2(3H)-one in 40 ml of ethanol was hydrogenated in the presence of 111 mg of palladium (10% on activated carbon) at RT and standard pressure for 5 d. The reaction mixture was then filtered through Celite and the residue was washed with ethanol. The combined filtrates were concentrated under reduced pressure. The residue was used for the next step without further purification. Yield: 626 mg (purity 88%, 58% of theory)
