Reaction Conditions

Reaction Steps

To a solution of methyl 3-chloro-2-(4-fluorophenyl)quinoxaline-6-carboxylate (130 mg, 0.41 mmol) in DMSO (2 mL) was added pyrrolidine (58 mg, 0.82 mmol) and DIEA (106 mg, 0.82 mmol). After stirring 2 h at 70° C., the reaction mixture was dissolved in water (100 mL), extracted with dichloromethane (3×30 mL), dried over anhydrous magnesium sulfate and concentrated under reduced pressure to afford a residue, which was purified via silica gel column chromatography (2% dichloromethane in petroleum ether) to afford methyl 2-(4-fluorophenyl)-3-(pyrrolidin-1-yl)quinoxaline-6-carboxylate as a light yellow solid (72 mg, 50%).
