Reaction Steps

To a suspension of 2-(4-aminophenyl)-4-(4-fluorophenyl)-5-(4-pyridyl)-1H-imidazole (80 mg, 0.24 mmol) [See Ex. 28 above] and triethylamine (0.12 mL, 0.86 mmol) in CH2Cl2 (5 mL) was added methanesulfonyl chloride (55 mL, 0.72 mmol). After stirring at rt for 1 h, the mixture was poured into aqueous NaHCO3 and extracted with EtOAc. The organic extract was washed with saturated aqueous NaCl, dried (MgSO4) and concentrated under reduced pressure. The residue was purified by flash chromatography, eluting with a solvent gradient of 2-10% MeOH/CHCl3 to afford the title compound as a tan solid (35 mg, 36%): ESMS (m/z): 409 (M++H).
