How is 3-((Methylamino)methyl)benzonitrile (CAS: 90389-96-1) typically synthesized?

3-((Methylamino)methyl)benzonitrile (CAS: 90389-96-1) is typically synthesized by the reaction of methylamine with benzonitrile in the presence of a base such as potassium carbonate or sodium hydroxide. The process involves heating the mixture to promote the nucleophilic substitution reaction. The yield is generally high, and the product can be isolated by simple distillation. This reaction is selective and is often used in pharmaceutical and industrial applications.
