Adding a certain compound to certain chemical reactions, such as: 3304-70-9, name is Dimethyl 4,5-imidazoledicarboxylate, 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 3304-70-9, Quality Control of Dimethyl 4,5-imidazoledicarboxylate
At ambient temperature 9.50 g (59.45 mmol) bromine were added dropwise to a solution of 9.90 g (53.76 mmol) dimethyl imidazole-4,5-dicarboxylate in 300 ml dichloromethane and 80 ml acetonitrile. 7.46 g (54.00 mmol) potassium carbonate was added, and the reaction mixture was stirred for 2 hours at ambient temperature. Then the dichloromethane was eliminated using the rotary evaporator and the residue was combined with a saturated solution of sodium chloride and sodium thiosulphate. It was extracted ten times with ethyl acetate, the organic extracts were dried over sodium sulphate and then the solvent was eliminated. Yield: 12.31 g (87% of theory) C7H7BrN2O4 (263.05) Mass spectrum: (M+H)+=263/265 (bromine)
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, Dimethyl 4,5-imidazoledicarboxylate, other downstream synthetic routes, hurry up and to see.
