930-62-1, name is 2,4-Dimethylimidazole, 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. Application In Synthesis of 2,4-Dimethylimidazole
PREPARATION 39 1-(3-Methyl-4-nitrophenyl)-2,4-dimethylimidazole STR118 A mixture of 5-fluoro-2-nitrotoluene (10.3 g), 2,4-dimethylimidazole (6.36 g) and sodium carbonate (7.5 g) was heated with stirring in dimethylformamide (40 cm3) at 130 for 40 hours. The cooled mixture was then concentrated in vacuo, the residue was acidified to pH1 with 4M hydrochloric acid, and the resulting solution was extracted with chloroform (2*25 cm3) to remove any neutral material. The combined aqueous phases were basified to pH10 with 2.5M sodium hydroxide solution and the mixture was extracted with chloroform (3*250 cm3). The combined and dried (MgSO4) organic extracts were concentrated in vacuo to give a solid which was chromatographed on silica (Merck “MK 60.9385” [Trade Mark]) eluding with methanol:ethyl acetate, 1:19. Combination and evaporation of appropriate fractions afforded a solid (8.4 g) which was recrystallized from ethyl acetate to give 1-(3-methyl-4-nitrophenyl)-2,4-dimethylimidazole, m.p. 135.5-138. Analysis %: Found: C, 62.0; H, 5.7; N, 17.9; Calculated for C12 H13 N3 O2: C, 62.3; H, 5.7; N, 18.2.
The synthetic route of 930-62-1 has been constantly updated, and we look forward to future research findings.
