Acetic Acid → HCID 12767920, compound

Participants

Reaction Steps

In 2 ml of acetic acid and 2 ml of acetic anhydride was dissolved 9.5 mg of 6-aminospiro[benzo[b]thiophene-2(3H),1'-cyclopropan]-3-one as obtained in Example 6, and the solution was stirred at room temperature for 10 minutes. The reaction solution was evaporated to dryness under reduced pressure, and the residue was chromatographed on a column of silica gel. Recrystallization of the resultant crude crystals from ethanol-water (1:2) yielded colorless needles of 6-acetylaminospiro[benzo[b]thiophene-2(3H),1'-cyclopropan]-3-one. Melting point: 195°-196.5° C.
