Hydrochloric Acid → 2-Amino-3-cycloheptylpropanoic acid

Participants

Reaction Steps

To a solution of 2-(Benzhydrylidene-amino)-3-cycloheptyl-propionic acid tert-butyl ester (1.34 g; 3.31 mmol) in methanol (5 mL) was added 10N HCl solution (15 mL) and the mixture heated to reflux. After 15 h, the mixture was allowed to cool to room temperature and transferred to a separatory funnel and washed with ethyl acetate. The aqueous layer was then neutralized with concentrated ammonium hydroxide solution and the white solid was filtered off and air dried to give 329 mg of 2-Amino-3-cycloheptyl-propionic acid.
