Reference of 33543-78-1, The chemical industry reduces the impact on the environment during synthesis 33543-78-1, name is Ethyl 1H-imidazole-2-carboxylate, I believe this compound will play a more active role in future production and life.
Example 3A Ethyl 1-[2-(2,4-dichlorophenyl)-2-oxoethyl]-1H-imidazole-2-carboxylate 0.5 g (3.6 mmol) of imidazole-2-carboxylate ethyl were dissolved in 35 ml of acetone, and 0.96 g (3.6 mmol) of 2-bromo-2,4-dichloroacetophenone and 0.49 g (3.6 mmol) of potassium carbonate were added. The mixture was stirred at RT for 12 h. The reaction mixture was concentrated and taken up in water and dichloromethane. The organic phase was washed with saturated aqueous sodium chloride solution, dried over magnesium sulfate and concentrated on a rotary evaporator. The residue was triturated with diethyl ether and the solid was filtered off with suction. This gave 0.9 g (77percent of theory) of the product as a solid. LCMS (method 1): Rt=1.19 min. (m/z=327 (M+H)+) 1H-NMR (400 MHz, DMSO-d6): delta=7.96 (d, 1H), 7.84 (d, 1H), 7.68 (dd, 1H), 7.5 (s, 1H), 7.16 (s, 1H), 5.87 (s, 2H), 4.22 (q, 2H), 3.32 (s, 2H), 1.23 (t, 3H).
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, Ethyl 1H-imidazole-2-carboxylate, other downstream synthetic routes, hurry up and to see.
