実験手順
To a mixture of methyl 3,3-dimethylbutanoate (500 mg, 3.84 mmol) in EtOH (12 ml) was added hydrazine monohydrate (1.87 ml, 38.4 mmol). The mixture was heated to 80° C. under reflux for overnight. The reaction was cooled back down to room temperature and concentrated to dryness affording a crude residue. The residue was dried under high vacuum to afford the title compound as crystalline solid (90 mg, 18% yield). 1H NMR (400 MHz, DMSO-d6) δ ppm 8.69-9.12 (s, 1H) 4.13 (br. s, 2H) 1.89 (s, 2H) 0.94 (s, 9H).
