Reaction Steps

Piperazinyl-benzimidazole-5-carboxamide (0.186 g, 0.5 mMol) was taken in 5 mL DMF and 0.101 g (1 mMol) triethylamine was added and stirred for 15 minutes at room temperature. To this reaction mixture was added 0.104 g 2,6-difluorobenzyl bromide and the mixture was stirred for 20 h. This was poured into water and extracted with methylene chloride (3×50 mL). The combined extract was further washed with brine, water and dried over MgSO4. The solvent was removed in vacuo and the residue chromatographed on silica gel eluting with chloroform-methanol (0 to 5% methanol, gradient). Evaporation of the desired fraction gave 48.9 mg of the desired product; MS(ESI) m/e 356 (M+).
