Reaction Steps
1-(Phenylsulfonyl)-6-(trimethylstannanyl)-1H-indazol-4-amine (4.2 g, 9.63 mmol), N-[5-bromo-2-(methyloxy)-3-pyridinyl]methanesulfonamide (3.25 g, 11.56 mmol) and Pd(PPh3)4 (1.113 g, 0.963 mmol) were weighed into a round-bottomed flask. DMF (30 ml) was added and the reaction was heated at 120° C. for 20 mins. The solvent was removed in vacuo and the crude material (9.8 g) was dissolved in DCM and loaded onto the top of a 750 g RediSep silica cartridge that was then eluted with 0-100% EtOAc/cyclohexane over 10 column volumes using the Companion XL. The product-containing fractions were combined and the solvent removed in vacuo to afford the title compound as a pale yellow solid (2.39 g).
