Participants

Reaction Steps

4-[2-[3-Methoxy-4-(2,3-epoxypropoxy)phenyl]-2-oxoethylthio]quinoline (Compound 57; 2.0 g, 5.25 mmol) was added at 0° C. to the mixture of formic acid (40 ml) and water (4 ml), and stirred at room temperature overnight. The solvent was removed under reduced pressure. The residue was added with an ice-cooled aqueous solution of 40% sodium hydroxide (7.0 ml) and stirred at 0° C. for 30 minutes. The solvent was removed under reduced pressure and the residue was chromatographed by silica gel column chromatography (dichloromethane:methanol=20:1) to obtain 1.4 g of the titled compound (67.0%). Melting Point: 177° C. (decomp.)
