To a solution of benzyl (1S,2S,3S,5S)-2-(tert-butyldimethylsilyloxy)bicyclo[3.1.0]hexan-3-ylcarbamate (2.0 g, 5.540 mmol) in THF (20) at room temperature was added 1 M tetrabutylammonium fluoride in THF (55 mL, 55.4 mmol), and the mixture was stirred at room temperature overnight. The reaction solution was diluted with ethyl acetate (100 mL), and washed with water (3×50 mL) and brine (50 mL). The organic layer was dried over sodium sulfate, filtered and concentrated to afford the title compound (1.2 g, 92%) as a white solid. MS (ES+) C14H17NO3 requires: 247, found: 230 [M+H−H2O]+.
