Application of 1849-02-1, The chemical industry reduces the impact on the environment during synthesis 1849-02-1, name is 2-Chloro-1-methyl-1H-benzo[d]imidazole, I believe this compound will play a more active role in future production and life.
b. 1-methyl-2-(Piperazin-1-yl)-benzimidazole A mixture of 1 g (6.02 mmol) of 2-chloro-1-methyl-benzimidazole and 2.58 g (30 mmol) of piperazine is heated to 150C. without a solvent. The cooled melt is combined successively with water and dilute hydrochloric acid and extracted with dichloromethane. Then the aqueous phase is made alkaline with dilute sodium hydroxide solution and extracted with dichloromethane. The organic phase is dried over sodium sulphate and concentrated by evaporation. The product is purified by column chromatography on silica gel (eluant: dichloromethane/ethanol/ammonia=5:1:0.1). Yield: 0.4 g (30.8% of theory), Melting point: 99 C.
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, 2-Chloro-1-methyl-1H-benzo[d]imidazole, other downstream synthetic routes, hurry up and to see.
