실험 절차

A mixture of 2-bromo-N-tert-butyl-5H-pyrrolo[3,2-b]pyrazine-7-carboxamide (0.1 g, 0.337 mmol), 7-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-1-((2-(trimethylsilyl)ethoxy)methyl)-1H-indazole (121 mg, 0.37 mmol), Pd2(dba)3 (39 mg, 0.067 mmol), X-Phos (64 mg, 0.135 mmol) and Na2CO3 (107 mg, 1.01 mmol) in dioxane (20 mL) and water (5 mL) was heated to 90° C. for 16 hours under N2 atmosphere. The reaction mixture was concentrated and the residue was partitioned between ethyl acetate (20 mL) and water (10 mL), organic phase was washed with brine (10 mL) then dried over Na2SO4 and concentrated to afford N-tert-butyl-2-(1-((2-(trimethylsilyl)ethoxy)methyl)-1H-indazol-7-yl)-5H-pyrrolo[3,2-b]pyrazine-7-carboxamide (120 mg, crude) as yellow oil. LCMS: (M+H)+=465.
