Triethylamine → HCID 86665362, compound

Participants

Reaction Steps

To a mixture of 250 mL dichloromethane with 10.1 g (100 mmol) of triethylamine is added 12.6 g (100 mmol) of 2,2-difluoro-3-hydroxypropanoic acid and the resulting mixture is placed into an ice bath. 10.5 g (100 mmol) of methacryloyl chloride is added slowly into the flask and reaction is kept stirring for overnight. The resulting mixture is then washed with 200 mL of 1% NaHCO3 solution and the solvent is then subsequently removed. The product is then recrystallized from methanol to provide 2,2-difluoro-3-(methacryloyloxy)propanoic acid, in expected good yield, which is used for following synthesis without further purifications.
