Synthetic Route of 73368-41-9, 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. 73368-41-9, name is Ethyl 4-amino-3-methoxybenzoate belongs to esters-buliding-blocks compound, it is a common compound, a new synthetic route is introduced below.
After adding acetonitrile (170 mL) and N-chlorosuccinimide (13.4 g, 100 mmol) to ethyl 4-amino-3-methoxybenzoate (17.8 g, 91.2 mmol) in that order, the mixture was stirred at 60 C. for 2 hours. The mixture was returned to room temperature, and the solvent in the mixture was distilled off under reduced pressure. The residue was purified by silica gel column chromatography (mixture of n-heptane and ethyl acetate: n-heptane/ethyl acetate=8/1 then 4/1) to obtain the title compound (15.8 g, 68.8 mmol). 1H-NMR (CDCl3) delta: 1.37 (t, J=6.8 Hz, 3H), 3.91 (s, 3H), 4.32 (q, J=6.8 Hz, 2H), 4.58 (br.s, 2H), 7.36 (d, J=1.8 Hz, 1H), 7.65 (d, J=1.8 Hz, 1H).
In the field of chemistry, the synthetic routes of compounds are constantly being developed and updated. I will also mention this compound in other articles, Ethyl 4-amino-3-methoxybenzoate, other downstream synthetic routes, hurry up and to see.
