Participants

Reaction Steps

Conc. sulfuric acid (8 ml) is added to N-(β-ethoxyacryloyl)-N-(1-benzoyl-4-piperidinyl)aniline (0.8 g) and the mixture is reacted at 60° C. for 30 minutes. The reaction mixture is poured into ice-water and then extracted with dichloromethane. The solvent is concentrated and the resulting residue is purified by silica gel column chromatography (solvent; dichloromethane:methanol=50:1) to give 1-(1-benzoyl-4-piperidinyl)carbostyril (0.53 g).
