Procedure

500 mg (2.4 mmol) of 3-(N′-phenyl-hydrazinocarbonyl)-propionic acid were dissolved in 10 ml of THF and 213 mg (0.7 mmol) of triphosgene were added. The reaction mixture was stirred at room temperature overnight. Then a saturated sodium hydrogencarbonate solution was added, and the mixture was evaporated to dryness under reduced pressure. The residue was purified by preparative RP HPLC eluting with a gradient of 0 to 100% acetonitrile in water (+0.01% TFA). After lyophilization, the product was obtained as a solid. Yield: 315 mg.
