Adding some certain compound to certain chemical reactions, such as: 152628-03-0, name is 4-Methyl-2-propyl-1H-benzo[d]imidazole-6-carboxylic acid, 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 152628-03-0. 152628-03-0
Example 1:Orthophosphoric acid (210 gms) was taken in round bottomed flask and Rho205 (210 gms) was added in portions with vigorous stirring. (Note: Sharp increase in temperature > 200 C). The above mass is allowed to cool to 70 C and 2-n-propyl- 4-methyl-benzimidazole-6-carboxylic acid (70 gms, 0.321 mol) was added slowly. Then N-methylbenzene-l,2-diamine hydrochloride (62.3 gms, 0.321 mol) was added in small portions at same temperature and then the temperature was raised to 125-130 C. After completion, reaction was quenched with ice cold water (1 Lt), adjusted pH of the reaction mixture to 9-10 by the addition of aqueous ammonia solution. Obtained solid was filtered and washed with cold water until the pH of the filtrate becomes neutral. Then the crude solid was washed with hot water until colorless filtrate was observed. The crude solid was boiled in ethyl acetate (700 ml) for 2-3 hrs. The reaction mass was cooled and the suspension was filtered off and dried to yield 2-n-propyl-4-methyl-6-(l-methylbenzimidazol-2-yl)-lH- benzimidazole (V) (80 gms, Yield : 82 %).
Chemical properties determine the actual use. Each compound has specific chemical properties and uses. We look forward to more synthetic routes in the future to expand reaction routes of 4-Methyl-2-propyl-1H-benzo[d]imidazole-6-carboxylic acid.
