Participants

Reaction Steps

To 0.20 g of (2E)-3-(1-(1,3-dioxolan-2-ylmethyl)-7-methoxy-2-oxo-1,2-dihydroquinolin-4-yl)-acrylamide, 5 mL of 80% aqueous trifluoroacetic acid solution was added, and stirred at room temperature for 4 hours, thereafter allowed to stand at the same temperature overnight. After the solvent was removed under reduced pressure, water was added and adjusted to pH 7.8 with 1.0 mol/L aqueous sodium hydroxide solution. The resulting solid was filtered to give 98 mg of (2E)-3-(7-methoxy-2-oxo-1-(2-oxoethyl)-1,2-dihydroquinolin-4-yl)acrylamide as a light brown solid.
