The compound is then reduced to N-2-amino-5-chloropyridazine-3-carboxamide using a reducing agent such as tin chloride in the presence of aqueous hydrochloric acid.
The final product is then hydrochlorified using hydrogen chloride gas to yield 4-PyridazineMethanaMine hydrochloride.

Route 2: via 2,4-Dinitrophenyl Pyridine
This synthetic route involves the synthesis of 2,4-dinitrophenyl pyridine using the reduction of 2,4-dinitrobenzaldehyde with sodium amalgam.
The resulting 2,4-dinitrophenyl pyridine is then nitrated using nitric acid to yield 2,4-dinitro-5-nitro-pyridine.
The compound is then condensed with methyl-mine using a condensation agent such as dicyclohexyl carbodiimide to yield 4-PyridazineMethanaMine hydrochloride.

Route 3: via N-Amino-5-chloropyridazine-3-carboxamide
This route involves the synthesis of N-amino-5-chloropyridazine-3-carboxamide using the reaction of chlorpyridazine with ammonia in the presence of an acid catalyst such as sulfuric acid.
The compound is then hydrochlorified using hydrogen chloride gas to yield 4-PyridazineMethanaMine hydrochloride.

Each of these synthetic routes has its own advantages and disadvantages, and the choice of route depends on factors such as the desired yield, cost, and availability of reagents.
In addition to the above-mentioned routes, other synthetic methods have also been reported in the literature.
