실험 절차

To 5.05 g (20.75 mmol) of the acid of step 2 dissolved in 40 mL DMF was added 1.92 g (20.75 mmol) aminoacetonitrile hydrochloride, 3.98 g (20.75 mmol) of EDCI, 2.80 g (20.75 mmol) of HOBT and 7.98 mL (72.63 mmol) of N-methylmorpholine. The reaction mixture was stirred at room temperature overnight, partitioned between ethyl acetate and water, dried over magnesium sulfate and concentrated to obtain 5.83 g of the crude tert-butyl (1S,2R)-2-{[(cyanomethyl)amino]carbonyl}cyclohexylcarbamate.
