In the presence of catalytic amount of hydrochloric acid, the Mannich reaction of 3-nitrobenzaldehyde (3-Chlorobenzaldehyde), aromatic amines and aromatic ketones can take place directly at 20~25℃. Fifteen corresponding Mannich bases (1a~1o), 1-aryl-3- arylamino [3-nitro(chloro) phenyl] acetone, were prepared with 68~87% yield. Some compounds were verified by elemental analysis, IR, ^1H NMR, MS. The reaction conditions were also discussed in this paper.
