Some common heterocyclic compound, 30148-21-1, name is Ethyl 1-methyl-1H-imidazole-2-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. Application In Synthesis of Ethyl 1-methyl-1H-imidazole-2-carboxylate
Step 6a. A solution of ethyl 1 -methyl- lH-imidazole-2-carboxy late (2.0 g, 13 mmol) in 8 ml cone. H2SO4 and 8 ml cone. HNO3 was stirred for 3 hours at 70C. The solution was diluted with H2O, then adjusted to pH 7-8 with aq Na2C03 solution and extracted with DCM. The organic layer was concentrated and chromatographed (silica, ethyl acetate/petroleum ether) to give the desired compound as yellow solid (0.9g, 34.7%). ESI- MS m/z = 200.20 [M+H]+
These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route 30148-21-1, its application will become more common.
