Reaction Conditions:

in i-Amyl alcohol at 150; for 2.5 h;Microwave irradiation;

Steps:

4.3. General procedure to synthesize compounds M084, 4-7 and 11-14

General procedure: A solution of 2-chloro-[1H]-benzimidazole (305 mg; 2 mmol) and appropriate amine (12 mmol) in methyl-1-butanol (4.0 mL) was irradiated in a microwave reactor at 150 °C (detected by IR infrared temperature sensor) for 2.5 h. The reaction mixture was concentrated under reduced pressure at 50 °C and the crude product was further purified by silica chromatography (200-300 mesh, eluting with petroleum ether/EtOAc = 2:1) to give the titled 2-aminobenzimidazoles in 65-95% yields.
