実験手順

4-Aminotetrahydropyran (245 mg, 2.42 mmol, 2.0 eq) and sodium tert-butoxide (233 mg, 2.42 mmol, 2.0 eq) were added to a stirred solution/suspension of 2-bromo-4-(6,6-dimethyl-4-oxo-3-trifluoromethyl-4,5,6,7-tetrahydro-indazol-1-yl)benzonitrile (500 mg, 1.21 mmol, 1.0 eq), palladium (II) acetate (14 mg, 0.06 mmol, 0.05 eq), and DPPF (67 mg, 0.12 mmol, 0.10 eq) in 3.75 mL of toluene. The reaction vial was capped, and the reaction mixture was heated 20 minutes at 120° C. under microwave irradiation. The reaction mixture was diluted with water and ethyl acetate and combined. The layers were separated, and the aqueous layer was extracted with ethyl acetate (3×). The combined organic layers were washed with brine, dried over sodium sulfate, filtered, and concentrated in vacuo. The residue was purified on a Biotage system (SiO2, hexanes-ethyl acetate) to afford 4-(6,6-dimethyl-4-oxo-3-trifluoromethyl-4,5,6,7-tetrahydro-indazol-1-yl)-2-(tetrahydro-pyran-4-ylamino)-benzonitrile (772 mg, 49%) as a tan solid: LC/MS (m/z): [M+H]+ 433.7. Further elution with ethyl acetate afforded 4-(6,6-dimethyl-4-oxo-3-trifluoromethyl-4,5,6,7-tetrahydro-indazol-1-yl)-2-(tetrahydro-pyran-4-ylamino)-benzamide (713 mg, 44%) as a yellow solid: LC/MS (m/z): [M+H]+ 451.2.
