Reaction Steps

A solution of 1.60 g (0.068 mol) of sodium in 300 ml of anhydrous methanol was treated with a solution of 53.5 g (0.510 mol) of pyridazine-3-carbonitrile in 100 ml of methanol and the mixture was stirred for 8 hours at 35° C. Then, 29 g of ammonium chloride were added and the mixture was refluxed for approximately 14 hours. The hot mixture was filtered and the solid was discarded. 53.3 g of the title compound were obtained from the cold mother liquor by means of filtration.
