実験手順
In a glass tube, a mixture of 4-chloro-1-(3-fluorophenyl)-7-methyl-1H-pyrazolo[3,4-b]pyridin-6(7H)-one (76 mg, 0.27 mmol), tris(dibenzylideneacetone)dipalladium (0) (12 mg), 2-dicyclohexylphosphino-2′-(N,N-dimethylamino)biphenyl (Dave-Phos, 12 mg), 3-amino-N-cyclopropyl-4-methylbenzamide (78 mg, 0.41 mmol) in THF (2 mL) was de-gassed slightly under reduced pressure or a vacuum. LiHMDS (0.82 mL of 1.0 M in THF solution, 821 mmol) was added slowly. The glass tube was sealed and placed in an oil bath at 60° C. for 1 h. The mixture was cooled to RT and treated with saturated ammonium chloride solution, then extracted twice with EtOAc. The combined EtOAc layers were washed with brine, dried and concentrated. The resulting crude material was purified by silica gel chromatography (80-100% EtOAc in hexanes) to provide the title compound as a tan crystalline solid. MS (ESI, pos.ion) m/z: 432.0 (M+1).
