30148-21-1, name is Ethyl 1-methyl-1H-imidazole-2-carboxylate, belongs to imidazoles-derivatives compound, is considered to be a conventional heterocyclic compound, which is widely used in drug synthesis. The chemical synthesis route is as follows. HPLC of Formula: C7H10N2O2
A solution of the methylimidazole (3.2 mL, 40.0 mmol) in 30 mL de CH3CN:Et3N (2:1) was cooled to -30 C and quickly added to a previously prepared solution of ethyl chloroformiate (7 mL, 66.0 mmol) in 10 mL of CH3CN. The mixture was stirred for 15h at rt. The solvents were removed under reduced pressure; the crude was re-dissolved in water (20 mL) and extracted with chloroform (3 ¡Á 20 mL). The organic fractions were dried and concentrated, and the resulting residue was purified by flash cromatography (aluminum oxide, 90% MeOH) to give 3.72 g of a crude ester residue which was directly used for the next step. A solution of this residue (1.5 g, 9.74 mmol) in 15 mL of aqueous NaOH (1 M) was refluxed for 1 h. The resulting mixture was acidified to pH 2.0 using HCl 10% (aprox.15 mL) and lyophilized. The crude was dissolved in MeOH and concentrated underreduced pressure to give 12 as a slighlty pink solid (1.2 g, 98%).
The synthetic route of 30148-21-1 has been constantly updated, and we look forward to future research findings.
