実験手順

8-(5-Fluoro-2-methylphenoxymethyl)-7-(2-methoxy-4-methoxymethoxyphenyl)-1,3,3-trimethyl-3,4-dihydro-1H-quinoxalin-2-one (Reference Compound No. 8-1, 2.73 g, 5.52 mmol) was dissolved in a mixed solution of 1,4-dioxane (25 mL) and methanol (5 mL), and 4N HCl/1,4-dioxane solution (7.0 mL, 28 mmol) was added thereto. After the reaction mixture was stirred at room temperature for 1 hour, the mixture was diluted with ethyl acetate (130 mL). The mixture was washed with aqueous sodium hydrogen carbonate solution (130 mL) and saturated brine (100 mL) successively, dried over anhydrous magnesium sulfate, and then the solvent was removed under reduced pressure to give the titled reference compound (2.41 g) as a pale yellow solid. (Yield 97%)
