To a solution of 2-(trimethylsilyl)ethyl (1S,2R,3S,5S)-2-(1,3-dioxoisoindolin-2-yl)bicyclo[3.1.0]hexan-3-ylcarbamate (1.5 g, 3.886 mmol) in ethanol (20 mL) at room temperature was added hydrazine (1.9 ml, 38.860 mmol), and the resulting mixture was stirred at 75° C. for 2 hours. The reaction solution was concentrated, and the residue was purified by silica gel column chromatography (ethyl acetate:petroleum ether=1:4) to afford the title compound (800 mg, 80%) as a light yellow semi-solid.
