Application of 152628-03-0, Each compound has different characteristics, and only by selecting the characteristics of the compound suitable for a specific situation can the compound be applied on a large scale. 152628-03-0, name is 4-Methyl-2-propyl-1H-benzo[d]imidazole-6-carboxylic acid, This compound has unique chemical properties. The synthetic route is as follows.
EXAMPLE 15; PREPARATION OF 2-n-PROPYL-4-METHYL-6-(1-BENZIMIDAZOLE-2-YL) BENZIMIDAZOLE (FORMULA XI); 5 g of 2-n-propyl-4-methyl-benzimiclazoltheta-6-carboxylic acid of Formula III, obtained in Example 1 , and 2.6 g of o-phenylenediamine, were charged into a round bottom flask containing 15 g of polyphosphoric acid (PPA). Reaction mass was heated to 150-155 C and maintained for 4-5 hours. Cooled the reaction mass to 70-80 C and charged 50 ml of water. Stirred for 45-60 minutes at the same temperature and then cooled to 10-15 C. Reaction mass pH was adjusted to 5-6 with 10% aqueous sodium hydroxide solution (200 ml) and stirred for 15-30 minutes. Filtered the solid and washed with 10 ml of water.The wet solid was charged into a flask and 50 ml of water was added. The contents were heated to 70-80 C and stirred for 30-45 minutes. Cooled to 25-35 C and stirred for 30-45 minutes. Filtered the solid and washed with 10 ml of water. Dried the solid at 50-55 C for 4-5 hours to afford 7.2 g of the title compound.
The chemical industry reduces the impact on the environment during synthesis 4-Methyl-2-propyl-1H-benzo[d]imidazole-6-carboxylic acid. I believe this compound will play a more active role in future production and life.
