실험 절차

A mixture of methyl 5-bromo-6-chloro-1H-indazole-3-carboxylate (50 mg, 0.17 mmol), triethylamine (0.05 mL, 0.4 mmol), tetrakis(triphenylphosphine)palladium(0) (10.7 mg, 0.009 mmol), copper iodide (3.0 mg, 0.017 mmol) and phenyl acetylene (20 mg, 0.20 mmol) in tetrahydrofuran (1.0 mL) was sealed and heated to 120° C. for 16 hours. The cooled reaction mixture was concentrated in vacuo and purified by flash chromatography utilizing heptanes/ethyl acetate (1:1 to 0:1) to give the title compound (20 mg) as a yellow solid. MS (ES−): 309.0 (M−H)− Step 2
