The Production Process of 6-Chloro-N-cyclopropylpyridazin-3-amine

The production process of 6-chloro-N-cyclopropylpyridazin-3-amine is a complex chemical reaction that involves several steps.
The starting materials for this process are 3-amino-6-bromo-pyridazine-2,4-diamine and hydrogen chloride gas.
The final product is a white or off-white crystalline solid that is soluble in water.

The production of 6-chloro-N-cyclopropylpyridazin-3-amine typically begins with the manufacture of 3-amino-6-bromo-pyridazine-2,4-diamine, which is obtained by a reaction between 2,4-diaminopyridine and hydrogen bromide.
This intermediate compound is then treated with hydrogen chloride gas under conditions that promote the deamination of the amine group.
The resulting 6-chloro-N-cyclopropylpyridazin-3-amine is then purified and dried to remove any residual impurities.

The production process of 6-chloro-N-cyclopropylpyridazin-3-amine can be broken down into the following steps:

1. Preparation of 2,4-diaminopyridine: This intermediate compound is synthesized by reacting pyridine with hydrogen chloride gas in the presence of a catalyst such as aluminum chloride.
   
2. Deamination of 2,4-diaminopyridine: 2,4-diaminopyridine is treated with hydrogen bromide in the presence of a solvent such as water to form 3-amino-6-bromo-pyridazine-2,4-diamine.
   
3. Treatment with hydrogen chloride gas: 3-amino-6-bromo-pyridazine-2,4-diamine is treated with hydrogen chloride gas under certain conditions, such as in the presence of a strong acid catalyst, to produce 6-chloro-N-cyclopropylpyridazin-3-amine.
   
4. Purification and isolation: The resulting 6-chloro-N-cyclopropylpyridazin-3-amine is purified and dried to remove any impurities that may have been introduced during the production process.
