A solution of 1-benzyl-4-(3-methylphenylamino)-isonipecotamide (4.5 g, 13.9 mmol) and potassium hydroxide (3.g, 53.5 mmol) in ethylene glycol (35 mL) was heated under reflux. The resulting mixture was diluted with water and neutralized with acetic acid. The white solid precipitated was filtered, washed with chloroform to provide 1-benzyl-4-(3-methylphenylamino)piperidine-4-carboxylic acid.
