(i)Chlorination with excess chlorine occurs at all available positions that are ortho and para tothe hydroxyl group.(j)Amines react with esters to give amides. In the case of a phenyl ester, phenol is the leavinggroup.(k)Aryl diazonium salts attack electron-rich aromatic rings, such as those of phenols, to give theproducts of electrophilic aromatic substitution.24.18In the frst step p-nitrophenol is alkylated on its phenolic oxygen with ethyl bromide.Reduction of the nitro group gives the corresponding arylamine.Treatment of p-ethoxyaniline with acetic anhydride gives phenacetin.1p-EthoxyanilineOCH2CH3H2NAceticanhydrideCH3COCCH3OOp-Ethoxyacetanilide(phenacetin)OCH2CH3CH3CNHOOCH2CH
