Versuchsvorschrift

To a solution of methyl 1-(6-chloropyridin-3-yl)cyclopropanecarboxylate (1 g, 0.005 mol) in pyridine (2 mL) was added hydrazine (0.30 mL, 0.0094 mol). The solution was heated at 90° C. overnight. The reaction solution was cooled to RT, and then diluted with a small amount of ice-water. The precipitate was collected by filtration, and dried under vacuum to afford the desired compound (0.9 g, 90%). Analytical LCMS: (M+H)+=208.0.
