Yield:129409-54-7 95.5%

Reaction Conditions:

with sulfuric acid at 20; for 48 h;

Steps:

19

Concentrated sulfuric acid (3 mL) was added slowly to a stirred solution of 2,4 di- fluorophenylacetic acid a (10.0 g, 58.1 mmol) in EtOH (100 mL), stirred at RT for 2 d. It was concentrated, diluted with EtOAc (200 mL), washed with 10% K₂CO₃ until the washes EPO were basic, dried (MgSO₄), and concentrated in vacuo to afford 11.1 g (95.5%) of difluoro ester b as a white solid.
