Versuchsvorschrift

2.9 g (12 mmol) of 5-tert-butyl-3-ethoxy-3H-isobenzofuran-1-one was weighed into a 50 mL round bottom flask fitted with a stir bar and cap. Added 10 mL (130 mmol) of hydrazine monohydrate. Added 15 mL of glacial acetic acid. Stirred at 100° overnight. Poured the reaction mixture into 200 mL of stirred water. Collected the solids by filtration and washed with water. Dried under high vacuum to obtain 2.24 g of the title compound as an off-white solid. MS (ESI) 203 (M+H)+.
