실험 절차

A suspension of (5-chloro-[1,2,4]triazolo[1,5-a]pyridin-8-yl)-[4-(4-methyl-piperazin-1-yl)-phenyl]-amine (50 mg, 146 μmol), 2-Fluoro-4-(4,4,5,5-tetramethyl-[1,3,2]dioxaborolan-2-yl)-benzamide (97 mg, 360 μmol), Pd(PPh3)4 (51 mg, 40 μmol) and NaOtBu (56 mg, 580 μmol) in 1.2 mL of DMF/water (5:1, degassed) is degassed for 1 min in a sealed tube. The tube is sealed and the reaction mixture heated at 110° C. for forty minutes in the microwave (CEM explorer) and then at the same temperature for thirty minutes in an oil bath. After evaporation of the solvents the residue is taken up in dichloromethane, filtered and evaporated. The crude product is purified by flash chromatography (silica gel, dichloromethane/7N NH3 in methanol 97:3 to 90:10) and triturated (3× with ethyl acetate) affording the title compound (12 mg) as a solid.
