1-Iodo-4-methoxybenzene (82.6 mg, 353 μmol, 2.00 equiv) was added under argon to a stirring reaction mixture of ethyl 3-(4-phenyl-1H-1,2,3-triazol-1-yl)-1H-pyrazole-4-carboxylate (50.0 mg, 177 μmol, 1.00 equiv), copper(I) iodide (16.8 mg, 88.3 μmol, 0.500 equiv), cyclohexane-1,2-diamine (40.3 mg, 42.4 μL, 177 μmol, 1.00 equiv) and dipotassium carbonate (73.2 mg, 530 μmol, 3.00 equiv) in dry N,N-dimethylformamide (2.0 mL). The reaction was stirred for 3 days at 100 °C. The reaction mixture was cooled down to 21 °C, diluted with water and extracted with ethyl acetate. The combined organic phase was washed with aq. sodium thiosulfate solution and brine, dried over Na2SO4 and filtered.
