Reaction Steps

tert-Butyl 6-((((9H-fluoren-9-yl)methoxy)carbonyl)amino)-3-azabicyclo[3.1.0]hexane-3-carboxylate (1.9 g, 1.0 eq.) was dissolved in DCM (20 mL) TFA (1.38 mL, 4 eq) was added dropwise at 0° C. and the reaction mixture was stirred at room temperature for 4 h. The reaction mixture was cooled to 0° C. and neutralized by saturated NaHCO3. The solid precipitated out was collected by filtration to afford 1.0 g of (9H-fluoren-9-yl)methyl 3-azabicyclo[3.1.0]hexan-6-ylcarbamate (69% yield).
