실험 절차

A vial was charged with a slurry of 4-(4-bromophenyl)-5-{[(3S)-1-(cyclopropylcarbonyl)-3-pyrrolidinyl]methyl}-2,4-dihydro-3H-1,2,4-triazol-3-one (100 mg, 0.256 mmol), (2,4-dichlorophenyl)boronic acid (98 mg, 0.511 mmol), tetrakis(triphenylphosphine)palladium(0) (29.5 mg, 0.026 mmol) and tripotassium phosphate (217 mg, 1.022 mmol) in ethanol (4.0 mL) and water (4.00 mL) then purged with nitrogen and sealed with a standard teflon septa (crimped aluminum seal). The reaction was heated in an aluminum block at 110° C. for 2 h. The cooled reaction was diluted with ethanol then evaporated under reduced pressure to a yellow residue. The residue was triturated from methanol and the filtered methanol layer was purified by reverse phase HPLC (LUNA C-18: 30×50 mm column; 20-70% acetonitrile w/0.1% TFA/water w/0.1% TFA). The desired product fractions were combined and evaporated in vacuo to a residue that was recrystallized from hexanes/ethyl acetate to afford the title compound as a white solid (26 mg, 21.8%). MS(ES)+ m/e 457.0, 459.2 [M+H]+, chlorine pattern.
