How is N-Methyl-1-(4-(trifluoromethyl)phenyl)methanamine (CAS: 90390-11-7) typically synthesized?

N-Methyl-1-(4-(trifluoromethyl)phenyl)methanamine is typically synthesized via a multistep process involving the protection of the amine group, followed by coupling of the 4-(trifluoromethyl)benzyl halide with an amine in the presence of a suitable base. Commonly used catalysts include triphenylphosphine and imidazoles. The yield is usually around 70-80%, with high selectivity for the desired product.
