Procedure

In a four-neck round bottomed flask (250 mL) which contained 3-hydrazinopyridine dihydrochloride (18.2 g, 0.100 mol) was added sodium ethoxide (21 wt % in ethanol, 107 g, 0.330 mol). The temperature of the slurry rose to 33° C. over 5 minutes. The mixture was stirred at room temperature for 1.25 hours. To the light red tinted slurry was added methyl acrylate (18.0 mL, 0.200 mol) over 10 minutes, with the temperature rising from 25° C. to 35° C. The color of the slurry changed from light red to brown/green. The mixture was heated at 55° C. for 3 hours. After stirring at room temperature overnight, the mixture was neutralized to pH ˜7 with hydrochloric acid (4 M in 1,4-dioxane, 32.6 g, 0.130 mol). The dark gray slurry was concentrated to a dark, paste like solid.
