How is 1-(4-Fluoro-3-nitrophenyl)methanamine (CAS: 771581-73-8) typically synthesized?

1-(4-Fluoro-3-nitrophenyl)methanamine can be synthesized by coupling 4-fluoro-3-nitrobenzoic acid with methylamine. The synthesis involves esterification of the carboxylic acid group followed by nucleophilic substitution with methylamine. The reaction is typically conducted under mild conditions with appropriate solvents and catalysts to ensure high selectivity and yield. Common solvents include acetonitrile or dichloromethane.
