실험 절차

To a mixture of N-(3-((5-bromothiazol-2-yl)amino)phenyl) methanesulfonamide 56 (0.159 g, 0.458 mmol), commercially available 4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)benzonitrile 57 (0.125 g, 0.545 mmol), Lithium chloride (0.038 g, 0.916 mmol) and tetrakis(triphenylphosphine)palladium (0.058 g, 0.05 mmol) in dry and degassed (using argon) 1,4-Dioxane (20 mL) was added aq. Na2CO3 (1M, 0.91 mL, 0.916 mmol). Reaction mixture was degassed again for 2-3 times for 10 minutes and resulting yellow mixture was stirred under argon at 100° C. for 14 hours. Reaction mixture was filtered through a small pad of celite and concentrated. Crude product was MPLC (Biotage) silica column chromatographed using Acetone:Hexane as an eluent to obtain N-(3-((5-(4-cyanophenyl)thiazol-2-yl)amino)phenyl)methanesulfonamide 58 (0.15 g, 89% yield). MS (ES) m/z 371 (M+H+).
