Procedure
To acetic anhydride (8 ml.) was added (8h) (400 mg., 1.06 mmole). After stirring for 1 hour at 90° C. the mixture was left to stand at room temperature for 18 hours, then evaporated to dryness under high vacuum. The product, an oil, was triturated in absolute ethanol, giving crystalline (9h), m.p. 111°-112° C. in 58.4% yield. Analysis (C20H17ClFNO6) C,H,N.
