Participants

Reaction Steps

To a solution of 6-(1-tert-butoxycarbonylamino-cyclopropyl)-nicotinic acid (0.50 g, 1.8 mmol) in DMF (3 mL) was added HATU (0.68 g, 1.8 mmol), Et3N (0.25 mL, 1.8 mmol) and the mixture allowed to stir at room temperature for 20 min. Hydrazine monohydrate (0.09 mL, 1.8 mmol) was then added and the reaction stirred for 1 h. The mixture was diluted with water and extracted with EtOAc (3×100 mL). The combined extracts were washed with water, brine and dried with MgSO4. The mixture was filtered and concentrated to give [1-(5-hydrazinocarbonyl-pyridin-2-yl)-cyclopropyl]-carbamic acid tert-butyl ester (0.51 g, 1.7 mmol) as a yellow solid, m/z 293.7 [M+H]+.
