실험 절차

A mixture of methyl 6-amino-5-iodonicotinate (111 mg, 0.40 mmol), N-(3-ethynylphenyl)-1,3-dimethyl-1H-pyrazole-5-carboxamide (144 mg, 0.60 mmol), triethylamine (0.167 ml, 1.2 mmol), dichlorobis(triphenylphosphine)palladium(II) (23 mg, 0.032 mmol) and triphenylphosphine (5.2 mg, 0.020 mmol) in 3.2 ml DMF at room temperature was degassed using vacuum and a balloon of H2, then copper(I)iodide (3.8 mg, 0.020 mmol) added. The reaction was heated at 60° C. for 1 hour 40 minutes, then partitioned between EtOAc and dilute brine. The EtOAc layer was dried with anhydrous Na2SO4 and rotary evaporated. The solid was recrystallized from EtOAc/hexane to give the title compound as a yellow-tan solid (122 mg, 78%).
