These common heterocyclic compound, 106429-57-6, name is Methyl 2-oxo-2,3-dihydro-1H-benzo[d]imidazole-5-carboxylate, its 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. Product Details of 106429-57-6

2-oxo- 2,3-dihydro-1 /-/-benzoimidazole-5-carboxylic acid methyl ester (3.00 g, 15.6 mmol) and phosphorus oxychloride (30 ml_) were combined and heated to 100 0C for 48 h. The mixture was cooled to 23 0C and concentrated under reduced pressure. The residue was cooled to 0 0C, and cold, saturated aqueous NaHCO3 (60 ml_) was added cautiously. After stirring at 23 0C for 15 min, the mixture was sonicated and the resulting residue was filtered to yield the titled compound (3.13 g, 95%), which was used in the next step without further purification. MS (ESI/CI): mass calcd. for C9H7CIN2O2, 210.02; m/z found, 211.0 [M+H]+.

The synthetic route is as follows., COA of Formula: C9H8N2O3

Potassium tert-butoxide (2.57 g) was added to a solution of 2-oxo-2,3-dihydro-1H-benzoimidazole-5-carboxylic acid methyl ester (2 g) in DMA (30 ml). Allyl bromide (2 ml) was added, and the mixture was stirred for 2 h at room temperature. The mixture was acidified with 2N aqueous HCl and then extracted with EtOAc. The combined organic layers were dried over Na2SO4 and then concentrated to an oil. The residue was purified by flash chromatography (SiO2, EtOAc/heptane 1:2) to give the title compound (2.2 g) as a yellow oil. MS (m/e)=273.2 [M+H+].

At the same time, in my other blogs, there are other synthetic methods of this type of compound, Methyl 2-oxo-2,3-dihydro-1H-benzo[d]imidazole-5-carboxylate, and friends who are interested can also refer to it.

Adding a certain compound to certain chemical reactions, such as: 106429-57-6, name is Methyl 2-oxo-2,3-dihydro-1H-benzo[d]imidazole-5-carboxylate, 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 106429-57-6, COA of Formula: C9H8N2O3

A suspension of benzimidazolone 2 (25.0 g, 0.130 mol, 1 eq) in POCl3 (150 mL) was heated to reflux for 7 h. The excess of POCl3 was evaporated and the residue was neutralized with saturated NaHCO3 solution. The precipitate was collected by filtration and dried in vacuo. The aqueous phase was extracted with DCM, dried over MgSO4 and the solvent was removed under reduced pressure. The light brown solids obtained this way were of high purity and could be used in the next step without further purification (19.7 g, 93.6 mmol, 72 %).
