Procedure

The procedure is the same as that used for preparing 2-phenyl-4-quinolinebutanoic acid described in Example 24, but starting with δ-oxo-2-phenyl-4-quinolinepentanoic acid (4.6 g), 98% pure hydrazine hydrate (2.15 g), potassium hydroxide pellets (2.4 g) and diethylene glycol (14 cc). 2-Phenyl-4-quinolinepentanoic acid (4 g) is thereby isolated, its proton NMR spectrum in deuterated chloroform showing the following characteristics:
