Procedure

2-Chloro-4,5-difluorobenzenesulfonamide (0.683 g), (tetrahydro-2H-pyran-4-yl)methanamine (0.346 g), N,N-diisopropylethylamine (0.681 ml) and dioxane (10 ml) were heated at 65° C. for 2.5 days. Additional (tetrahydro-2H-pyran-4-yl)methanamine (0.346 g) and N,N-diisopropylethylamine (0.681 ml) were added and heating was continued at 70° C. for 1.5 days. The reaction mixture was concentrated and column chromatographed on silica gel with 0-3% methanol in dichloromethane as eluent. The obtained solid was triturated with dichloromethane to give the title compound.
