Reaction Steps

To a suspension of 4-[1-methyl-4-phenyl-5(4pyridyl)-imidazol-2-yl]benzoic acid, sodium salt (20 mg, 0.06 mmol) [See Ex. 5 above] in CH2Cl2 (2 mL) was added triethylamine (24 mL, 0.17 mmol), followed by thionyl chloride (10 mL, 0.14 mmol). The reaction mixture was stirred at rt for 30 min, at which time MeOH (0.5 mL) was added. The mixture was stirred at rt for an additional 2 h and concentrated under reduced pressure. The residue was purified by flash chromatography, eluting with a solvent gradient of 0-1% MeOH/CHCl3 and recrystallized from EtOAc to afford the title compound as an off-white crystalline solid (1.6 mg, 8%): mp 208°-209° C.
