Versuchsvorschrift
To a solution of benzyl [(1R)-2-amino-1-methyl-2-oxoethyl]carbamate (10 g, 45 mmol) in 50 mL of N,N-dimethylformamide was added 2,4,6-trichloro-1,3,5-triazine (4.15 g, 22.5 mmol). After 2 h, 100 mL of water was added and the mixture was filtered. The solids were washed with 100 mL aqueous sodium bicarbonate (2×) and dried under vacuum to give pure benzyl [(1R)-1-cyanoethyl]carbamate (7.2 g). MS 205.2 ((M+1).
