反応手順
To a solution of Example 63B (0.9 g, 3.1 mmol) in dioxane (10 mL) were added hydrazine (0.12 mL, 3.7 mmol, Aldrich) and acetic acid (0.35 mL, 6.2 mmol). After stirring at 85° C. for 16 h, the reaction mixture was cooled and quenched with saturated NaHCO3 (10 mL). The aqueous layer was extracted with ethyl acetate (3×20 mL). The combined organic extracts were dried over anhydrous Na2SO4, filtered and concentrated under reduced pressure to provide the title compound. MS (APCI+) m/z 238 (M+H)+.
