Water → Benzenemethanamine, 3-chloro-N-methyl-

To a solution of methylamine (2.0 M solution in tetrahydrofuran, 30 ml) in N,N-dimethylformamide (30 ml), 3-chlorobenzyl chloride (2.5 ml) was added, and the mixture was stirred at room temperature for 4.5 hours. Water was added to the reaction solution, followed by extraction with ethyl acetate. The extract was washed with water and saturated saline in this order and then dried over anhydrous sodium sulfate. The solvent was distilled off under reduced pressure to obtain a crude product of the title compound, which was used in the next reaction without being purified.
