In a microwave tube were charged with of (S)-tert-butyl (1-(5-amino-3-bromopyridin-2-yl)-2-(3,5-difluorophenyl)ethyl)carbamate (46A, 350 mg, 0.8 mmol), N-(4-chloro-1-methyl-7-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-1H-indazol-3-yl)methanesulfonamide (410 mg, 1.06 mmol) and PdCl2[P(Cy)3]2 (18 mg, 0.025 mmol). To the mixture was added 16 mL of 1,4-dioxane and 4.9 mL of sodium bicarbonate aqueous solution (1M). The system was purged with argon and then the microwave tube was sealed and the reaction mixture was heated up in a heating bath at 150° C. for 1 hour. After cooling to room temperature, the reaction was partitioned between EtOAc and water. The organic layer was separated and washed with brine, then dried over MgSO4, filtered and concentrated. The residue was purified by silica gel chromatography eluting with EtOAc/hexanes to afford the title product. MS (m/z): 606.88 [M+H]+.
