Reaction Steps
A mixture of 1321 g of 1,1,1-trichloro-2-hydroxy-4-methyl-4-pentene, 695 g of acetic anhydride, and 32.6 ml of pyridine was heated at 95°-100° for 1 hour. The low boiling by-products were removed under vacuum, and the residue was then distilled, yielding 1276 g of 1,1,1-trichloro-2-acetoxy-4-methyl-4-pentene; bp, 87°/5.5 mm.
