Reaction Steps
A stirred suspension of 4-{2-amino-4-[3-(2-fluoropyridin-3-yl)phenyl]-1-methyl-5-oxo-4,5-dihydro-1H-imidazol-4-yl}-1-ethyl-1H-pyrrole-2-carbaldehyde (0.10 g; 0.25 mmol), in THF (5 mL), was added methoxylamine hydrochloride (0.021 g; 0.25 eq). The mixture was stirred at reflux temperature for 2 hours. The mixture was cooled and the solvent was evaporated. The residue was dissolved in dichloromethane and washed with water. The dichloromethane solution was dried over MgSO4, filtered and evaporated. The resultant residue was crystallized from ethyl acetate and hexane to yield the title compound, 0.069 g (64% yield), mp 190-193° C., MS (ES) m/z 433.1; [M−H]
