A mixture of 2-(3-isopropyl-2-oxo-2,3-dihydro-benzoimidazol-1-ylmethyl)-1-(3-methyl-butyl)-1H-benzoimidazole-5 carboxylic acid (42 mg, 0.1 mmol), EDC (23 mg, 0.12 mmol), DMAP (14 mg, 0.12 mmol) and dimethylamine (1M in THF, 0.12 mL) was stirred for 12 h at ambient temperature. The solvent was evaporated and the residue purified by prep-HPLC (gradient 10%-100% B) to give 22 mg (49%) of 2-(3-isopropyl-2-oxo-2,3-dihydro-benzoimidazol-1-ylmethyl)-1-(3-methyl-butyl)-1H-benzoimidazole-5-carboxylic acid dimethylamide as a white solid.
