Formic Acid → HCID 118079722, compound

Participants

Reaction Steps

Sodium formate (14 mg, 0.200 mmol) and formic acid (46 mg, 1.0 mmol) were added to (S)-furan-2-yl(3-methyl-7-(4-(methylsulfonyl)phenyl)-3,4-dihydroquinoxaline-1(2H)-yl)methanone (0.2 M in 1,2-dichloroethane, 0.1 mL, 0.02 mmol) and shaken at room temperature for 5 h. The reaction was concentrated and the crude product was purified by mass-triggered preparatory HPLC. The product-containing fractions were combined and concentrated to afford (S)-4-(furan-2-carbonyl)-2-methyl-6-(4-(methylsulfonyl)phenyl)-3,4-dihydroquinoxaline-1(2H)-carbaldehyde (0.0061 g, 72%). MS (ESI, pos. ion) m/z 425.
