실험 절차

In a 10 mL flask was added 4-(4,4,5,5-tetramethyl-[1,3,2]dioxaborolan-2-yl)-1-(2,4,6-trimethyl-benzenesulfonyl)-1H-pyrrole-2-carboxylic acid methyl ester (1.0 equivalent, 0.34 mmol, 149 mg), (4-chloro-[1,3,5]triazin-2-yl)-phenyl-amine (1.1 equivalent, 0.37 mmol, 78 mg), tetrakistriphenylphosphine palladium (0.2 equivalent, 0.07 mmol, 80 mg), sodium carbonate (1 mL, 2 N), methanol (1 mL) and benzene (5 mL). The resulting mixture was heated at 80° C. for 2 hours then diluted in ethyl acetate and washed with water, brine. The organic layer was dried over sodium sulfate then concentrated under vacuum. The crude mixture was then purified by prep HPLC to afford 55 mg of the title compound. HPLC, Rt=8.8 min, FIA, ES+=478.1.
