Reaction Steps

A mixture of 8-benzoyloxymethyl-7-(5-fluoro-2-methoxyphenyl)-3,3-dimethyl-3,4-dihydro-1H-quinoxalin-2-one (Compound No. 1-3, 42.9 mg, 0.099 mmol), methyliodide (30.7 μL, 0.49 mmol), and cessium carbonate (89.0 mg, 0.27 mmol) was suspended in anhydrous N,N-dimethylformamide (1 mL) and stirred at room temperature for 1.5 hours. The reaction mixture was diluted with ethyl acetate (100 mL). The mixture was washed with water (100 mL) and saturated brine (50 mL) successively, dried over anhydrous magnesium sulfate, and then the solvent was removed under reduced pressure. The obtained residue was purified by silica gel column chromatography (hexane-ethyl acetate) to give the titled compound (35.0 mg) as a colorless amorphous product. (Yield 79%)
