Procedure

2-[(Ethoxycarbonyl)methyl]benzimidazole-5-carboxylic acid (1.0 eq) was dissolved in THF. HBTU (1.1 eq) and diisopropylethylamine (2.0 eq) were added, followed by dimethylamine (2.0 M in THF, 1.1 eq). The reaction was stirred at room temperature overnight then concentrated and the residue was purified by silica gel chromatography (5:95 MeOH/CH2Cl2) to afford the desired compound. LC/MS m/z 276.2 (MH+), Rt 1.18 minutes.
