Methyl iodide → HCID 66831368, compound

Participants

Reaction Steps

A suspension of 3-(3,5-difluorophenyl)-2-ethyl-6-fluoroquinolin-4(1H)-one (280 mg, 0.9 mmol) in DMF (5 mL) was treated with NaH (60%, 1.5 eq, 55.3 mg). After 30 min, MeI (0.12 mL, 2.0 eq) was added dropwise and the reaction mixture was stirred at rt overnight before quenching with water. The reaction mixture was extracted with EtOAc (5 mL×2). The organic layers were combined washed with water, brine, dried, concd and purified by column chromatography on silica gel (EtOAc/hexane, 1/2) to give 3-(3,5-difluorophenyl)-2-ethyl-6-fluoro-1-methylquinolin-4(1H)-one as a white solid. Mass Spectrum (ESI) m/e=318 (M+1).
