Pyridazine, 3,6-dione, and 4-bromo-1,2-dihydro-pyridazine are synthesized through different chemical reactions.
Pyridazine, 3,6-dione is synthesized through a four-step reaction process.
The first step involves the reaction of acetamide with maleic anhydride in the presence of an acid catalyst to form N-acetyl-N-(3,6-dioxo-1,2,4-triazaspiro[4,5]decane-8-yl) carboxamide.
The second step involves the hydrolysis of the obtained product to form 3,6-dioxa-1,2,4-triazaspiro[4,5]decane-8-amine.
The third step involves the cyclization of the amine to form 3,6-dioxa-1,2,4-triazaspiro[4,5]decene-8-amine.
The final step involves the reduction of the obtained product to form Pyridazine, 3,6-dione.

4-bromo-1,2-dihydro-pyridazine is synthesized through a two-step reaction process.
The first step involves the reaction of 4-bromoaniline with formaldehyde in the presence of an acid catalyst to form 4-bromo-1,2-dihydro-2H-pyrazol-3-one.
The second step involves the reduction of the obtained product to form 4-bromo-1,2-dihydro-pyridazine.
