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. 2297-06-5, name is Methyl 4-amino-2-sulfamoylbenzoate belongs to amides-buliding-blocks compound, it is a common compound, a new synthetic route is introduced below. Computed Properties of C8H10N2O4S
SYNTHESIS EXAMPLE 5 Synthesis of preparation intermediate, methyl 2-(aminosulfonyl)-4-(2,5-dihydro-3,4-dimethyl-2,5-dioxo-1H-pyrrol-1-yl)benzoate (Compound No. II-B-4) In 3 ml of acetic acid, 1 mmol of methyl 4-amino-2-(aminosulfonyl)benzoate and 1.05 mmol of 2,3-dimethylmaleic anhydride were stirred at 80 C. for 40 hours. Acetic acid was then distilled off from the reaction mixture, followed by the addition of 20 ml of ice water to the oily residue. After the mixture thus formed was stirred for 2 hours, the resulting precipitate was collected by filtration and then dried in air. Yield: 43%. Its physiocochemical properties are shown in Table 8.
The synthetic route of 2297-06-5 has been constantly updated, and we look forward to future research findings.
