Researchers who often do experiments know that organic synthesis is a process of preparing more complex target molecules from simple raw materials through one or more chemical reactions. Generally, it requires fewer steps, and cheap raw materials. 830-43-3, name is 4-(Trifluoromethyl)benzenesulfonamide, A new synthetic method of this compound is introduced below., Recommanded Product: 830-43-3
EXAMPLE 159 Synthesis of 1-(2-chlorobenzyl)-2-methyl-6-[4-(trifluoromethyl)benzenesulfonylcarbamoyl]benzimidazole (221) In the same manner as in Example 158, 0.390 g of 1-(2-chlorobenzyl)-2-methyl-6-[4-(trifluoromethyl)benzenesulfonylcarbamoyl]benzimidazole (221) were formed from 0.450 g of 6-carboxy-1-(2-chlorobenzyl)-2-methylbenzimidazole, 0.486 g of N,N’-carbonyldiimidazole, 0.676 g of 4-(trifluoromethyl)benzenesulfonamide and 0.457 g of diazabicycloundecene.
The basis of chemical reaction formula synthesis, the synthesis route is composed of some specific reactions and combined according to certain logical thinking. We look forward to the emergence of more reaction modes in the future.
