실험 절차
5-Aminospiro[benzo[b]furan-2(3H),1'-cyclopropane]-3-one (0.875 g.) was acetylated with acetic anhydride (7 ml.) and acetic acid (7 ml.) and the acetylation product was recrystallized from ethanol. By the above procedure there was obtained 5-acetylaminospiro[benzo[b]furan-2(3H),1'-cyclopropane]-3-one as yellow prisms melting at 211°-212° C.
