Hydroxylation of both the aromatic ring and side chain then takes place, followed by an oxidation of the pyrrolidine ring to the corresponding lactam, with subsequent detachment and ring opening to the corresponding carboxylic acid.
A series of chemical reactions follows, starting with the oxidation of both the aromatic ring and side chain. This is followed by the hydroxylation of the pyrrolidine ring, leading to the formation of a lactam, which is subsequently cleaved and converted into a carboxylic acid.
