Participants

Reaction Steps

To a solution of cyclopropyl carboxylic acid (0.20 g, 0.68 mmol) in DMF (2 mL) was added HATU (0.26 g, 0.68 mmol), Et3N (0.10 mL, 0.75 mmol) and the reaction mixture was allowed to stir at room temperature for 20 min. [1-(5-Hydrazinocarbonyl-pyridin-2-yl)-cyclopropyl]-carbamic acid tert-butyl ester (0.20 g, 0.68 mmol) in DMF (1 mL) was added and the reaction allowed to stir at room temperature for 21 h. The mixture was diluted with water and extracted with EtOAc (3×100 mL). The combined extracts were washed with satd NaHCO3, brine and dried with MgSO4. The mixture was filtered and concentrated to give {1-[5-(N′-cyclopropane-carbonyl-hydrazinocarbonyl)-pyridin-2-yl]-cyclopropyl}-carbamic acid tert-butyl ester (0.23 g, 0.64 mmol) as a light brown solid, m/z 361.7 [M+H]+.
