How is 1-(3-Chloro-2-thienyl)methanamine (CAS: 214759-25-8) typically synthesized?

1-(3-Chloro-2-thienyl)methanamine can be synthesized through the nucleophilic substitution of thienyl chloride with methylamine in the presence of a base like sodium hydride. The yield is generally around 70-80%, and the selectivity towards the desired product can be improved by using appropriate reaction conditions and solvents. The reaction is exothermic and requires careful temperature control to avoid side reactions.
