How can you synthesise nicotine?

Nicotine can be synthesized through various chemical methods, one common approach being the alkylation of pyridine with methyl iodide or through the use of more complex synthetic routes involving the condensation of pyridine and other reagents. Additionally, it can be extracted from tobacco plants, where it naturally occurs in higher concentrations. Synthetic routes may vary in complexity and yield, often influenced by the desired purity and scale of production.
