Yield:871239-62-2 96%

Reaction Conditions:

with isocyanuric acid in N,N-dimethyl-formamide at 20; for 2 h;

Steps:

4.2 Step 2: Synthesis of tert-butyl (lR,5S,6r)-6-cyano-3-azabicyclo[3.1.0]hexane-3- carboxylate

To a 50-mL round-bottom flask was added tert-butyl (lS,5R)-6-carbamoyl-3- azabicyclo[3.1.0]hexane-3-carboxylate (1.00 g, 4.42 mmol, 1 equiv) and cyanuric acid (815 mg, 4.42 mmol, 1 equiv) in DMF (17 mL). The reaction was stirred for 2 hours at room (0434) temperature. After 2 hours, the reaction was diluted with water and extracted 3 times with i- PrOAc. The organic layer was then washed 2 times with water and then brine, dried over a2S04, and concentrated under vacuum to afford tert-butyl (lS,5R)-6-cyano-3-azabicyclo [3.1.0]hexane-3-carboxylate as a clear yellow oil which crystallized over time (879 mg, 96% yield).
