Reaction Steps
A solution of tert-butyl 2-difluoromethyl-2-carbethoxypropionate (392 g) (prepared in Step B) in trifluoroacetic acid (TFA) (400 ml) is stirred at room temperature for several hours, then the excess TFA is removed by evaporation at reduced pressure. The residue is treated with carbon tetrachloride and re-evaporated.
