Product 1

HCID 128512414,5-dihydro-2,4-dimethyl-6-(4-pyridinyl)-3(2H)-pyridazinone

Procedure

Following the procedure described in Example A-16 but using in place of methyl 4-cyano-4-(4-morpholinyl)-4-(4-pyridinyl)-2-methylbutanoate a molar equivalent quantity of methyl 2-methyl-4-oxo-4-(4-pyridinyl)butanoate, it is contemplated that there can be obtained 4,5-dihydro-2,4-dimethyl-6-(4-pyridinyl)-3(2H)-pyridazinone. Also, this same compound can be obtained following the procedure described in Example A-1 but using in place of 4-oxo-4-(4-pyridinyl)butanenitrile a molar equivalent quantity of 2-methyl-4-oxo-4-(4-pyridinyl)butanenitrile.
