Procedure
A slurry of 0.8 g. sodium acetate (9.8 mmoles) and 16.0 g. II (54.6 mmoles) in 200 ml. acetic anhydride was refluxed until a color change to a tannish solution was noted. The solution was cooled to room temperature and diluted with 200 ml. EtOH:Acetone 3:2. The solution was filtered and the precipitate was slurried in an additional 200 ml. EtOH:Acetone 3:2 then filtered. The precipitate was dried under high vacuum giving 10.23 g. III (68.1%).
