الإجراء التجريبي

550 mg (3.97 mmol) of potassium carbonate and 350 mg (3.31 mmol) of methyl mercaptoacetate are added to a solution of 600 mg (3.31 mmol) of 3-methoxy-2-nitrobenzaldehyde in 8 ml of DMF. The reaction mixture is heated at 70° C. for 4 h. After cooling, water is added. The resulting precipitate is filtered off, washed with water and dried under reduced pressure. This gives 387 mg (45.7% of theory) of the title compound.
