実験手順

A 5 mL microwave reaction vessel was charged with 1-(2,4-Bis-trifluoromethyl-benzyl)-3-iodo-1H-indazole-5-carbaldehyde (300 mg, 0.6 mmol), copper (I) cyanide (135 mg, 1.5 mmol), and N,N-dimethylformamide (4 mL). The vessel was sealed and subjected to microwave irradiation at 185° C. for 15 min. The reaction mixture was partitioned between EtOAc and water. The organic layers were washed with brine, dried over Na2SO4, and evaporated. The crude residue was purified by flash column chromatography on silica gel, eluting with EtOAc/hexanes (1:4 v/v), to afford the title compound as a white solid.
