Procedure

To a solution of 1-benzoylamino-cyclopropanecarboxylic acid (5.0 g, 21.3 mmol) in DMF (5 mL) was added Et3N (2.94 mL, 21.3 mmol) and HATU (8.08 g, 21.3 mmol). The reaction mixture was allowed to stir for 10 min then hydrazinecarboxylic acid tert-butyl ester (2.81 g, 21.3 mmol) was added. The reaction was allowed to stir at room temperature overnight. The mixture was diluted with water and extracted with EtOAc (3×50 mL). The combined extracts were washed with saturated NaHCO3, 2N HCl, brine and dried with MgSO4. The mixture was filtered, concentrated in vacuo, and purified by silica gel chromatography (25-100% EtOAc in hexanes) to give the N′-(1-benzyloxy-carbonylamino-cyclopropyl)-hydrazinecarboxylic acid tert-butyl ester (6.2 g, 17.7 mmol) as a white solid, m/z 250.6 [M−101]+.
