Adding a certain compound to certain chemical reactions, such as: 109012-23-9, name is Ethyl 1-methyl-4-nitro-1H-imidazole-2-carboxylate, belongs to imidazoles-derivatives compound, 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 109012-23-9, Application In Synthesis of Ethyl 1-methyl-4-nitro-1H-imidazole-2-carboxylate
Ethyl 1-methyl-4-nitroimidazole-2-carboxylate17 (6, 613 mg, 3.1 mmol) was hydrogenated over 5% palladium on charcoal in ethanol. The resulting amino compound was dried thoroughly under vacuum to remove traces of ethanol. It was then dissolved in dichloromethane (20.0 mL) and the solution was cooled to 0-5 C. To the cold solution was added triethylamine (0.5 mL, 3.7 mmol) followed by benzoyl chloride (0.4 mL, 3.4 mmol). The reaction mixture was allowed to attain room temperature and then stirred for 12 h. Upon completion, the reaction was quenched with water (15.0 mL) and stirred for 15 min. The organic layer was separated and aqueous layer was washed with dichloromethane (2 × 10 mL). Combined organic layers were dried over sodium sulfate and evaporated to obtain a yellow oil. The crude product was purified by column chromatography using silica gel and 2% methanol in chloroform as the eluent system to obtain 7 as a yellow solid (808 mg, 96%).
