Related Products of 33543-78-1,Some common heterocyclic compound, 33543-78-1, name is Ethyl 1H-imidazole-2-carboxylate, molecular formula is C6H8N2O2, 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.
a) 1-(2-Trimethylsilanyl-ethoxymethyl)-1H-imidazole-2-carboxylic acid ethyl ester A flask charged with 1H-imidazole-2-carboxylic acid ethyl ester (1.03 g, 7.36 mmol), K2CO3 (2.00 g, 14.5 mmol), SEM-Cl (1.56 mL, 8.89 mmol), and 20 mL of acetone was stirred for 10 h at RT. The reaction was diluted with EtOAc (100 mL), washed with NaHCO3 (2*100 mL), brine (100 mL), and the organic layer dried over Na2SO4 and concentrated. The title compound was eluted from a 20-g SPE with 50percent EtOAc/hexanes to give 1.50 g (76percent) of a colorless oil. Mass spectrum (ESI, m/z): Calcd. for C12H22N3O3Si, 271.1 (M+H), found 271.1.
These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route Ethyl 1H-imidazole-2-carboxylate, its application will become more common.
