Reaction Conditions

Reaction Steps

To a degassed solution of acetonitrile (4 mL) and water (1 mL) were added potassium carbonate (4 eq, 2.8 mmol), 3-(5-chloro-2-thienyl)-1-isobutyl-4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-1H-pyrazole (1 eq, 0.7 mmol), 4-bromoquinoline (1 eq, 0.7 mmol) and 1,1′-bis(diphenylphosphinoferrocene)palladium(II)dichloride (0.1 eq, 0.07 mmol). The mixture was stirred at 130° C. in the microwave for 60 min. The solvent was evaporated and water and dichloromethane were added. The aqueous layer was extracted two times with dichloromethane. The combined organic extracts were dried over MgSO4 filtered and concentrated. The residue was purified by chromatography on silica gel (dichloromethane:methanol 1:0 to 9:1) to afford 45 mg of 4-[3-(5-chloro-2-thienyl)-1-isobutyl-1H-pyrazol-4-yl]quino line (15% yield).
