実験手順
A slurry of 6-4 (4 g, 13.39 mmol), hydrazine hydrate (1.261 ml, 40.2 mmol) and potassium carbonate (5.55 g, 40.2 mmol) in 2-MeTHF (100 ml) was heated at 80° C. for 16 h. After cooling to room temperature, the reaction mixture was partitioned between water and ethyl acetate. The organic layer was separated, dried over sodium sulfate, filtered and concentrated to afford Intermediate 6 as a tan solid. MS: m/z=295.4 (M+H).
