PROCEDURE
实验过程
A mixture of methyl 2-bromo-5-(pivaloyloxymethyl)-5H-pyrrolo[3,2-b]pyrazine-7-carboxylate (0.3 g, 0.81 mmol), 1-methyl-3-(tributylstannyl)-6-(trifluoromethyl)-1H-indazole (0.98 g, 1.51 mmol), Pd(PPh3)4 (174 mg, 0.151 mmol) and CuI (58 mg, 0.302 mmol) in dry DMF (10 mL) was heated to 90° C. for 3 hours. Water (10 mL) was added. The formed precipitate was separated by filtration, washed with petroleum ether (3 mL) to afford methyl 2-(1-methyl-6-(trifluoromethyl)-1H-indazol-3-yl)-5-(pivaloyloxymethyl)-5H-pyrrolo[3,2-b]pyrazine-7-carboxylate (200 mg, 50%) as a white solid. LCMS: (M+H)+=490.
