実験手順

To a solution of Benzo[1,3]dioxole-5-carbonitrile (5.0 g, 33.9 mmol) in EtOH (100 mL) was added hydroxylamine hydrochloride (4.68 g, 67.90 mmol) and NaOH (2.71 g, 67.9 mmol). The resulting reaction mixture was refluxed for 12 h. After the completion of the reaction (TLC monitoring), the mixture was concentrated, added EtOH and filtered. The filtrate was evaporated under reduced pressure and used as such for the next step (crude yield 4.8 g, 78.68%).
