N-(2-cyano-4-fluorophenyl)methanesulfonamide

Conditions: temp:0.00; pressure:0.00; stir:

Conditions: temp:120.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: (Step 1) A suspension of 2,5-difluorobenzonitrile (12.4 g), methanesulfonamide (9.3 g) and potassium carbonate (13.6 g) in DMSO (360 ml) was stirred overnight at 120° C. The reaction solution was poured into 1N hydrochloric acid, and extracted with ethyl acetate. The organic layer was washed with saturated brine, dried over magnesium sulfate, and filtered. The solvent was evaporated under reduced pressure. The residue was crystallized from ethyl acetate-hexane to give N-(2-cyano-4-fluorophenyl]methanesulfonamide (6.57 g) as a white solid. extracted with ethyl acetate The organic layer was washed with saturated brine dried over magnesium sulfate filtered The solvent was evaporated under reduced pressure The residue was crystallized from ethyl acetate-hexane
