Reaction Steps

A mixture of 5-(6-chloropyridin-3-yl)-1-methylpyridin-2(1 H)-one (1.2 g, 5.44 mmol) and hydrazine (870 mg, 2.2 mmol) in 2-propanol (5ml) was heated in a microwave at 140° C. for 5 hrs. The reaction mixture was co-evaporated with MeOH (3×) and then suspended in water (50 ml). Solid product was collected by filtration and dried under high vacuum for 24 hrs to provide the title compound, 5-(6-hydrazinylpyridin-3-yl)-1-methylpyridin-2(1 H)-one (600 mg, 51% yield).
