2-Bromo-N-(1-hydroxy-2-methylpropan-2-yl)-5-((2-(trimethylsilyl)ethoxy)methyl)-5H-pyrrolo[2,3-b]pyrazine-7-carboxamide (110 mg, 248 μmol) was dissolved in toluene (1.4 mL), and copper (I) iodide (2.49 mg, 27.8 μmol), sodium iodide (74.4 mg, 496 μmol) and trans-N,N′-dimethylcyclohexane-1,2-diamine (9.00 mg, 63.3 μmol) added. The mixture was sealed under nitrogen and the mixture heated at 110° C. After 15 h, 5-chloro-3-methyl-1H-indazole (41.3 mg, 248 μmol) and potassium phosphate tribasic (111 mg 521 μmol) were added, the mixture degassed under vacuum, backfilled with nitrogen, and the mixture heated at in sealed tube at 110° C. for 24 h. The mixture was cooled, filtered, and the cake washed with ethyl acetate. The combined filtrates were concentrated and purified by chromatography (silica, 24 g Analogix column, 0-40% ethyl acetate in hexanes) to give 2-(5-Chloro-3-methyl-1H-indazol-1-yl)-N-(1-hydroxy-2-methylpropan-2-yl)-5-((2-(trimethylsilyl)ethoxy)methyl)-5H-pyrrolo[2,3-b]pyrazine-7-carboxamide
