Procedure
A mixture of 8-(5-fluoro-2-methylphenoxymethyl)-7-(4-hydroxy-2-methoxyphenyl)-1,3,3-trimethyl-3,4-dihydro-1H-quinoxalin-2-one (Compound No. 11, 153 mg, 0.340 mmol), 1,1′-carbonyldiimiazole (95.6 mg, 0.590 mmol), and 4-dimethylaminopyridine (5.2 mg, 0.043 mmol) was dissolved in anhydrous tetrahydrofuran (3 mL) and stirred for 1 hour at room temperature. After morpholine (58.3 μL, 0.666 mmol) was added to the reaction mixture and the mixture was stirred for 2 hour, the mixture was purified by silica gel column chromatography (hexane-ethyl acetate) to give the titled compound (61.2 mg) as a colorless solid. (Yield 32%)
