Versuchsvorschrift
A solution of 120 mg (0.689 mmol) of 2,6-difluoro-3-methoxyphenyl)methanol from Example 132A in 3 ml of dichloromethane and 1 ml of thionyl chloride was stirred at room temperature overnight. The solvent was evaporated off under reduced pressure and the residue was purified by flash chromatography using a prepacked silica gel cartridge (eluent:cyclohexane-ethyl acetate 10:1 to 1:1), which gave 50 mg (38% of theory) of the target compound.
