Reaction Steps

A mixture of 3-fluorophenol (2.24 g, 20.0 mmol), ethyl 2-bromo-2,2-difluoroacetate (8.12 g, 40.0 mmol) and K2CO3 (6.91 g, 50.0 mmol) in MeOH (20 mL) was stirred at 70° C. overnight. It was then cooled to rt and filtered and the filtrate was concentrated in vacuo to give the title compound, which was used for next step without further purification.
