Acetic Anhydride → Methyl 2,2-dimethyl-3-(1-acetoxy-2,2-dichloro-3,3,3-trifluoropropyl)cyclopropanecarboxylate

Participants

Reaction Steps

To 50 mg (0.16 mmol) of methyl 2,2-dimethyl-3-(1-hydroxy-2,2-dichloro-3,3,3-trifluoropropyl)cyclopropanecarboxylate obtained in Example 1, 0.2 ml of acetic anhydride and 0.2 ml of pyridine were added, and the mixture was left overnight at room temperature. In the same manner as in Example 9, 53 mg of methyl 2,2-dimethyl-3-(1-acetoxy-2,2-dichloro-3,3,3-trifluoropropyl)cyclopropanecarboxylate was obtained as a colorless oily substance. Yield: 93%. The physical property values were the same as those in Example 7.
