Participants

Reaction Steps

To a solution of 5-chloro-N-((1-(2-(methylthio)-4-(2-oxopyridin-1(2H)-yl)phenyl)-1H-imidazol-4-yl)methyl)thiophene-2-carboxamide prepared above (16 mg, 0.035 mmol) in acetone (1 mL), mCPBA (70%, 12 mg, 0.049 mmol) was added. After being stirred at room temperature for 30 min, the mixture was purified by HPLC to give the sulfoxide (5 mg) and sulfone (3 mg). MS 473.0 and 475.0 (M+H, Cl pattern) for sulfoxide and 489.0 and 491.0 (M+H, Cl pattern) for sulfone.
