Reaktionsschritte

The title compound was prepared according to the method described in J. Chem. Soc., p. 3830 (1959). A solution of 4-chloropyridine (16.5 g, 145 mmol) and hydrazine monohydrate (7.76 mL, 160 mmol) in 1-propanol (50 mL) was heated under reflux for 18 hours. The solution was cooled to 0° C., and the resulting crystals were collected by filtration. The crystals were washed with cold 1-propanol and air dried to give the title compound (15.2 g, 72% yield). The compound was used in the following process without further purification.
