Application of 46004-37-9, 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. 46004-37-9, name is Methyl 4-amino-2-chlorobenzoate belongs to esters-buliding-blocks compound, it is a common compound, a new synthetic route is introduced below.
2-chloro-4-aminobenzoic acid, methyl ester (13.95 g) was suspended in a mixture of water (65 ml) and concentrated hydrochloric acid (15.7 ml). After stirring at room temperature for 10 minutes, the suspension was cooled to 0 C. A solution of sodium nitrite (5.71 g) in water (37 ml) was gradually added over 20 minutes, maintaining a reaction temperature of 0 C. After stirring at 0 C. for 35 minutes, the reaction mixture was partially neutralized by the addition of solid sodium carbonate (3.16 g) to afford a cold solution of the diazonium salt.
The synthetic route of Methyl 4-amino-2-chlorobenzoate has been constantly updated, and we look forward to future research findings.
