Reaction Steps

To a solution of 2-(4-aminomethylphenyl)-1-methyl-4-phenyl-5-(4-pyridyl)imidazole (30 mg, 0.09 mmol) [See Ex. 4 above] in pyridine (3 mL) was added acetic anhydride (0.30 mL, 3.18 mmol). The resulting solution was stirred at rt for 30 min, then concentrated under reduced pressure. The residue was purified by flash chromatography, eluting with a solvent gradient of 0-2% MeOH/CHCl3. The isolated material was triturated with Et2O to provide an off-white solid (10 mg, 28%) which was recrystallized from EtOAc to provide the title compound: mp 210-211° C.
