Methyl iodide → HCID 12668461, compound

Participants

Reaction Steps

2-(1H-benzo[d]imidazol-2-yl)benzenamine (525 mg, 2.5 mmol) in 5 mL dry THF was cooled to −78 degrees before 1 mL n-Bu-Li (2.5 mmol, 2.5 N in hexanes) was added via a syringe. The reaction was stirred at −78 degrees for 20 min and MeI (360 mg, 2.6 mmol) was added. The reaction was warmed to r.t. gradually and kept at room temperature for another hour. The reaction crude was diluted with 25 mL ether and the resulted suspension was filtered off the solid. The crude product was isolated after the solvent was removed from the collected filtrate to product 510 mg of 2-(1-methyl-1H-benzo[d]imidazol-2-yl)benzenamine in greater than 95% purity (MS, M++H=224.1).
