Related Products of 51605-32-4,Some common heterocyclic compound, 51605-32-4, name is Ethyl 5-methyl-1H-imidazole-4-carboxylate, molecular formula is C7H10N2O2, traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc, below Introduce a new synthetic route.
[2793] To a stirred solution of 994 (3.08 g, 20 mmol) in 15 ml of DMF at 0¡ã C. was added NaH (60percent in mineral oil, 0.80 g) portionwise. After stirring for several minutes, SEM-CI (3.54 ml, 20 mmol) was added and let the reaction stir overnight. Brine was added to the reaction and extracted with EtOAc. The organic layer was washed with water and brine, dried with MgSO4, filtered and concentrated under vacuum. Purified by flash elute column chromatography (CH2Cl2/MeOH, 50:1 to 20:1) to afford 4.54 g of yellow oil, compound 995.
These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route Ethyl 5-methyl-1H-imidazole-4-carboxylate, its application will become more common.
