Versuchsvorschrift
To a 0° C. solution of (1-carbamoyl-cyclopropyl)-carbamic acid benzyl ester (1.8 g, 7.7 mmol) in DMF (20 mL) was added cyanuric chloride in one portion. The reaction was allowed to warm to room temperature overnight. The reaction was quenched with water and extracted with EtOAc (3×100 mL). The combined extracts were washed with water (3×50 mL), brine and dried with MgSO4. The mixture was filtered and concentrated. The resulting crude residue was dissolved in 30% EtOAc in hexanes (90 mL) and filtered through a plug of silica gel. The filtrate was concentrated to give (1-cyano-cyclopropyl)-carbamic acid benzyl ester (1.4 g, 6.5 mmol) as a white foam.
