To synthesize the new moclobemide derivatives, research the antidepressant activity of moclobemide, filter the new antidepressant drugs of potential activity and side effects. This thesis is based on synthesized series morpholine derivative made in the eraly days. And then the bromoethylaminehydrobromide is synthetised by using ethanolamine as raw material and bromination. After this, 4-chloro-N-( 2-bromo-ethyl ) -benzamide is prepared for Chlorobenzeneformyl chloride reaction;Finally, serial moclobemide derivative is synthetised by making al...
