Adding a certain compound to certain chemical reactions, such as: 46004-37-9, name is Methyl 4-amino-2-chlorobenzoate, belongs to esters-buliding-blocks compound, can increase the reaction rate and produce products with better performance than those obtained under traditional synthetic methods. Here is a downstream synthesis route of the compound 46004-37-9, Product Details of 46004-37-9
Methyl-2-chloro-4-(methylsulfonamido) benzoate (101).; To a stirred solution of methyl-2-chloro-4-amino benzoate 100 (0.457 g, 2.45 mmol) in DCM cooled to 0 0C was added pyridine (2 mL) followed by dropwise addition of methanesulphonyl choride (0.2 mL, 2.5 mmol). After addition was complete, the reaction was allowed to warm to room temperature and stirred for 2 h. After completion, the reaction mixture was concentrated in vacuo. 1 N HCl (5 mL) was added to the residue and the mixture extracted with EtOAc (10 mL). The organic phase was dried over Na2SO4 and concentrated under high vacuum. The crude compound was purified by column chromatography to afford the title intermediate 101 as a solid (0.54 g, 84% yield).
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, Methyl 4-amino-2-chlorobenzoate, other downstream synthetic routes, hurry up and to see.
