To a solution of ethyl (1SR, 2 SR, 5RS, 6RS) 3-tert-butoxycarbonyl-4-oxo-3-azabicyclo[3.1.0]hexane-2,6-dicarboxylate (312 mg, 0.9 mmol) in dry THF (6 mL) under argon was added methylamine (2.74 mL, 5.4 mmol) and potassium cyanide (3 mg, 0.05 mmol). After stirring overnight in an ultrasonic bath, the solvent was removed under reduced pressure. The residue was directly purified by flash chromatography (hexane/ethyl acetate 1/1) to give 272 mg of the desired compound (80% yield).
