Continuously updated synthesis method about 4093-29-2

The synthetic route of Methyl 4-acetamido-2-methoxybenzoate has been constantly updated, and we look forward to future research findings.

4093-29-2, In the next few decades, the world population will flourish. As the population grows rapidly and people all over the world use more and more resources, all industries must consider their environmental impact. 4093-29-2, name is Methyl 4-acetamido-2-methoxybenzoate belongs to amides-buliding-blocks compound, it is a common compound, a new synthetic route is introduced below.

To methyl 4-acetamido-2-methoxybenzoate (299 mg, 1.34 mmol) in acetic anhydride (3 ml) stirred under nitrogen at -10 C was added concentrated nitric acid (0.35 ml) dropwise. After then stirring at 0 C for 10 min the reaction mixture was partitioned between ethyl acetate (20 ml) and water (20 ml). The aqueous layer was further extracted with ethyl acetate (2 x 10 ml) and the combined organic extract washed with saturated sodium bicarbonate solution (2 x 10 ml), brine (2 x 10 ml), dried (MgSO_ and evaporated to give methyl 4-acetamido-2-methoxy-5 -nitrobenzoate (301 mg, 84%) as a dull orange powder. nmr (400 MHz, CDC13) delta 2.33, s, 3H, AcNH; 3.91, s, 3H, 2-MeO or COOMe; 4.03, s, 3H, COOMe or 2-MeO; 8.63, s, IH, H3 or H6; 8.84, s, IH, H6 or H3; 10.89, br, NH.

The synthetic route of Methyl 4-acetamido-2-methoxybenzoate has been constantly updated, and we look forward to future research findings.
