Participants

Reaction Steps

To 1.2 g (4.5 mmole) of (-)-2-(4-fluoro-3-trifluoromethylphenoxy)butanoic acid dissolved in 15 ml methylene chloride was added one drop of pyridine and further added dropwise 0.6 g of thionyl chloride. The reaction mixture was further stirred at room temperature for 4 hours and then thionyl chloride and methylene chloride were removed under reduced pressure to obtain 1.2 g of (-)-2-(4-fluoro3-trifluoromethylphenoxy)butanoic acid chloride. The resulting mixture was applied for the next reaction without purification.
