Procedure

5N Sodium hydroxide (0.50 ml) was added to the compound (methyl 2-fluoro-3-[3-oxo-4-(2-(trimethylsilyl)ethoxymethyl)-3,4-dihydroquinoxaline-2-yl]benzoate) (283 mg) obtained in Working Example 28-2) in methanol (2 ml). The mixture was stirred at room temperature for 2 hours. After adding the mixture to 5N hydrochloric acid, the mixture was extracted with chloroform. The organic layer was dried over magnesium sulfate, filtered, and concentrated in vacuo to give the title compound (285 mg) as a crude material, which was served in the subsequent reaction without purification.
