Reaction Steps

Dissolve (1S,2S,4S,5R,6R)-4-acetyloxy-2-(tert-butoxycarbonyl)aminobicyclo[3.1.0]hexane-2,6-dicarboxylic acid diethyl ester (1.25 g, 3.13 mmol, Preparation 19) in a solution of 95% TFA in dichloromethane (60 mL) and stir under nitrogen at room temperature for 5 minutes. After this time remove the TFA/dichloromethane in vacuo. Dissolve the crude product in a suspension of NaHCO3 (1.00 g) in dichloromethane (50 mL) and stir for 30 minutes. Filter the suspension, wash with dichloromethane (3×25 mL), and concentrate in vacuo to afford 916 mg (98%) of the product as a yellow oil.
