Methyl iodide → HCID 67107877, compound

Participants

Reaction Steps

To a cold (0° C.) slurry of 50% sodium hydride (84 mg, 1.75 mmol) in THF (3 mL) was added 2-isopropyl-4-[1-methyl-1-(3-nitro-phenyl)-ethyl]-1H-imidazole (0.4 g, 1.46 mmol). The mixture was warmed to r.t. and stirred for 30 min. Iodomethane (0.13 mL, 2.1 mmol) was added and the reaction maintained for 2 h. The solvent was evaporated under reduced pressure and the residue partitioned between DCM and water. The organic phase was dried over sodium sulfate, filtered and concentrated. The residue was purified by column chromatography on silica gel (60-120 mesh), eluting with 25% ethyl acetate/hexane to obtain 2-isopropyl-1-methyl-5-[1-methyl-1-(3-nitro-phenyl)-ethyl]-1H-imidazole (0.148 g, 35%) as a colourless semisolid.
