How is N-Methylcyclopentanamine hydrochloride (CAS: 75098-42-9) typically synthesized?

N-Methylcyclopentanamine hydrochloride (CAS: 75098-42-9) is typically synthesized through the reaction of cyclopentanamine with methyl iodide followed by protonation with hydrochloric acid. This process involves the substitution of a hydrogen atom with a methyl group, followed by acidification to form the hydrochloride salt. The reaction is carried out in an inert solvent like dichloromethane under room temperature conditions with a yield of approximately 85%.
