Synthetic Route of 42122-75-8, 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. 42122-75-8, name is Methyl 5-amino-2-chlorobenzoate belongs to esters-buliding-blocks compound, it is a common compound, a new synthetic route is introduced below.
Example (Ik-2) 2-Chloro-5-({[1-methyl-3-(pentafluoroethyl)-4-(trifluoromethyl)-1H-pyrazol-5-yl]carbonyl}amino)benzoic acid 6.74 g (36.3 mmol) of methyl 5-amino-2-chlorobenzoate, 0.22 g (1.8 mmol) of 4-N,N-dimethylaminopyridine and 9.49 ml (54.4 mmol) of N-ethyldiisopropylamine are dissolved in 50.0 ml of ethyl acetate and cooled to 0 C. A solution of 6.0 g (18.1 mmol) of 1-methyl-3-(pentafluoroethyl)-4-(trifluoromethyl)-1H-pyrazole-5-carbonyl chloride in 100 ml of ethyl acetate is added over the course of an hour to this reaction mixture. When the addition is complete, the reaction mixture is stirred at room temperature for 16 hours. The reaction mixture is diluted with 250 ml of ethyl acetate and the organic phase is then washed three times with in each case 100 ml of 1M hydrochloric acid, three times with 1M sodium hydroxide solution and once with saturated sodium chloride solution. This gives 8.0 g of a mixture of methyl 2-chloro-5-({[1-methyl-3-(pentafluoroethyl)-4-(trifluoromethyl)-1H-pyrazol-5-yl]carbonyl}amino)benzoate and methyl 5-(bis{[1-methyl-3-(pentafluoroethyl)-4-(trifluoromethyl)-1H-pyrazol-5-yl]carbonyl}amino)-2-chlorobenzoate in the ratio 6:4.
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 5-amino-2-chlorobenzoate, other downstream synthetic routes, hurry up and to see.
