Versuchsvorschrift
To a solution of ethyl N-(3-aminopyridin-2-yl)glycinate (18 g) in THF (200 mL) was added CDI (15 g) at room temperature, and the mixture was stirred at room temperature overnight. The mixture was concentrated under reduced pressure. The residual crystals were washed with AcOEt to give the title compound (5.5 g).
