Participants

Reaction Steps

1.00 g of 6-[3-chloro-4-(hydrazinocarbonylmethoxy)phenyl]-4,5-dihydro-3(2H)-pyridazinone (Compound No. 18a, prepared following the procedure described in Example 4) was dissolved in 55 ml of dimethylformamide, and 2.3 g of p-anisaldehyde were added, at room temperature, to the resulting solution. The mixture was then stirred at the same temperature for 8 hours. At the end of this time, the solvent was distilled off in vacuo and chloroform was added to the resulting residue. The resulting precipitate was filtered off to give 1.28 g of the title compound melting at 220°-222° C.
