Procedure

Working as in example 2 for the preparation of N-(2,4-dichlorobenzyl)-3-oxo-6-pyridin-4-yl-2,3-dihydropyridazine-4-carboxamide, but starting with 0.3 g of 3-oxo-6-pyridin-2-yl-2,3-dihydropyridazine-4-carboxylic acid, 10 cm3 of dichloromethane, 1 cm3 of dimethylformamide, 0.12 cm3 of oxalyl chloride, 0.21 cm3 of 2,4-dichlorobenzylamine and 0.22 cm3 of triethylamine, 0.22 g of N-(2,4-dichlorobenzyl)-3-oxo-6-pyridin-2-yl-2,3-dihydropyridazine-4-carboxamide was obtained in the form of a cream-colored solid melting at a temperature above 260° C.
