6-Bromo-1-methyl-1H-indazol-4-amine (340 mg), sodium carbonate (638 mg) and Pd(dppf)Cl2 (110 mg) were weighed to a 10-20 ml microwave vial. {6-Chloro-5-[(methylsulfonyl)amino]-3-pyridinyl}boronic acid (377 mg) dissolved in 1,4-dioxane (6 ml) was added followed by water (6 ml). The reaction was heated for 15 min at 120° C. in the microwave. The reaction was passed through a 2 g silica cartridge, washing with methanol. The solvent was evaporated under nitrogen blow down. The residue was purified on the ISCO companion using a 40 g silica cartridge and a gradient of 2-8% methanol in DCM (containing 1% ammonia) over 15 mins at 40 ml/min. Product-containing fractions were combined and dried down to give title compound (158 mg).
