Procedure

A solution of tert-butyl 1-(2-(tert-butyldimethylsilyloxy)ethyl)cyclopropylcarbamate (11.9 g, 37.8 mmol) and 3HF.TEA (22.0 g) in DCM (50 mL) was stirred at rt for 17 hrs. The mixture was concentrated and the residue was purified by silica gel column chromatography (0˜20% gradient elution EtOAc/petroleum ether) to afford tert-butyl 1-(2-hydroxyethyl)cyclopropylcarbamate (4.6 g, 60%) as a white solid.
