실험 절차

A mixture of 3-iodo-1-methyl-5-phenyl-1H-pyrazolo[3,4-c]pyridazin-4-ol (100 mg, 0.28 mmol), copper iodide (11 mg, 0.056 mmol), L-proline (13 mg, 0.11 mmol), K2CO3 (193 mmol, 1.4 mmol) in anhydrous DMF (5.6 mL) was degassed by bubbling nitrogen through for 10 minutes, then heated to 110° C. for 20 h. The mixture was left to cool to room temperature, then partitioned between ethyl acetate and water, and the aqueous phase was extracted with ethyl acetate. The organic phases were combined, dried (MgSO4), filtered and evaporated. The residue (117 mg) was used as such in the next step.
