Versuchsvorschrift

To a solution of methyl 6-[tert-butoxycarbonyl-(2-ethoxy-2-oxo-acetyl)amino]norbornane-2-carboxylate, 72f, (0.80 g, 2.17 mmol) in methanol (20 mL) was added NaOH (4.33 mL of 2N solution, 8.66 mmol) at room temperature. The reaction mixture was stirred overnight. The mixture was diluted into 0.5 N HCl in ice, and extracted twice with EtOAc. The combined organic phases were dried (Na2SO4), filtered and concentrated in vacuo to afford 600 mg of desired product that was used without further purification
