実験手順
(S)-tert-butyl (1-(3-bromopyridin-2-yl)-2-(3,5-difluorophenyl)ethyl)carbamate (1.0 g, 2.42 mmol), N-(4-chloro-1-methyl-7-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-1H-indazol-3-yl)methanesulfonamide (1.12 g, 2.90 mmol), and PdCl2[P(cy)3]2 (89.0 mg, 0.121 mmol) were suspended in 1,4-dioxane (108 mL) and 1.0 M aqueous NaHCO3 (36 mL). The reaction mixture was degassed by bubbling argon for 5 minutes then sealed and heated 150° C. for 15 minutes in a microwave reactor. Upon cooling, the reaction mixture was diluted with water and extracted with three portions of EtOAc. The combined organic layers were dried over Na2SO4, filtered, concentrated in vacuo, and purified by silica gel column chromatography, eluting with 0-100% EtOAc in hexanes to give the title compound. MS (m/z) 591.72 [M+H]+.
