Reaction Conditions

Reaction Steps

To a solution of methyl 3-chloro-2-(4-fluorophenyl)quinoxaline-6-carboxylate (250 mg, 0.79 mmol) in DMSO (3 mL) was added cyclopentylamine (402.6 mg, 4.73 mmol), and the resulting solution was stirred overnight at 100° C. The resulting mixture was diluted with water (15 mL) and extracted with dichloromethane (3×10 mL), and the organic layers combined, dried over anhydrous magnesium sulfate, and concentrated in vacuo to give a residue, which was purified via silica gel column chromatography (2%-5% ethyl acetate in petroleum ether) to afford methyl 3-(cyclopentylamino)-2-(4-fluorophenyl)quinoxaline-6-carboxylate as a yellow solid (240 mg, 69%).
