1-(1-Methylethyl)-1H-imidazole Use and Manufacturing

Methods of Manufacturing

General procedure: Imidazole (3)/benzimidazole(5) (10 mmol) was dissolved in 10 ml of DMSO and solid NaOH(15 mmol) was then added it. The resulting pale yellow suspensionwas stirred in air at room temperature for 1.5 h, after which, thealkyl bromides or benzyl chlorides (15 mmol) were added andallowed to react until completion (TLC). Water (50 ml) was thenadded and the products were extracted with ethyl acetate. Combinedorganic layers were washed several times with water, thenwith brine, dried over Na2SO4 and subjected to chromatographicpurification over silica (100–200 mesh) using MeOH: EtOAc 5:95(v/v) as the mobile phase. Compounds 4a-f were isolated as yellowoils whereas, the compounds 7a-e were white solid. Spectroscopic data of the N-alkyl imidazoles are in accord with earlier literatureand thus are not shown here [30].A) EXAMPLE 4
