Procedure: Following a procedure analogous to the procedure described in Example 1 using N-{3-[5-(2-chloro-4-pyrimidinyl)-2-(1,1-dimethylethyl)-1,3-thiazol-4-yl]-2-fluorophenyl}-2,6-difluorobenzenesulfonamide (100 mg, 0.186 mmol) and tetrahydro-2H-thiopyran-4-amine (100 mg, 0.853 mmol) the title compound was obtained as a crude yellow foam and used directly in the next step. MS (ESI): 620.2 [M+H]+.

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

Procedure: 2-Bromo-4-(3-difluoromethyl-6,6-dimethyl-4-oxo-4,5,6,7-tetrahydro-indazol-1-yl)-benzamide (300 mg, 0.76 mmol), Pd(OAc)2 (8.7 mg, 5 mol %), DPPF (44.5 mg, 10 mol %) and NaOtBu (153 mg, 1.52 mmol) were added to a microwave vial. Toluene (1 mL) and 4-aminotetrahydrothiopyran (116 mg, 1.3 mol eq) were added and the vial was evacuated and back-filled with N2. The reaction mixture was heated at 120° C. for 15 min (microwave). The reaction mixture was filtered and the solids washed with CH2Cl2. The product was purified using flash chromatography eluting with hexanes and EtOAc. Product was recovered as an off-white solid (70 mg, 21%). The preceding product pyrazole (70 mg, 0.16 mmol) was dissolved in ethanol (0.8 mL) and DMSO (0.2 mL) to which NaOH (5 N, 65 mL, 2 eq) was added and the reaction mixture was heated at 70° C. for 12 hours. The reaction mixture was washed with H2O and EtOAc. The product was purified using flash chromatography eluting with hexanes and EtOAc. The title compound was obtained as an off-white solid (40 mg, 56% yield), LC/MS (m/z): M+H=449.2. the vial was evacuated back-filled with N2 The reaction mixture was filtered the solids washed with CH2Cl2 The product was purified eluting with hexanes and EtOAc Product was recovered as an off-white solid (70 mg, 21%) the reaction mixture was heated at 70° C. for 12 hours The reaction mixture was washed with H2O and EtOAc The product was purified eluting with hexanes and EtOAc
