Participants

Reaction Steps

A solution of 120 mg (0.710 mmol) of 2,4-difluoro-3-(hydroxymethyl)benzonitrile from Example 134A in 3 ml of dichloromethane and 1 ml of thionyl chloride was stirred at room temperature for 3 h. 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 60 mg (45% of theory) of the target compound.
