Reaction Steps

To 2,5-dichloro-1H-benzimidazole (100 mg, Synth. Commun, 1998, 28, 9, 1703-12) and Boc-piperazine (150 mg) was added dry EtOH (5 mL) and then triethylamine (0.112 mL) and the reaction was heated in a microwave at 150° C. for 1 h. The reaction was then heated further for 2.5 h at 170° C. The solvent was then evaporated in vacuo and the residue purified by column chromatography 30-100% EtOAC:hexanes to afford the title compound (72 mg) as a colourless oil.
