Procedure

To 2.7 g of 2-acetylamino-3-(2-quinolon-4-yl)propionic acid was added 30 ml of 20%-hydrochloric acid and the mixture was refluxed for 3 hours. The reaction mixture was concentrated under a reduced pressure to dryness, the residue obtained was recrystallized from ethanol-water to obtain 1.9 g of 2-amino-3-(2-quinolon-4-yl)propionic acid hydrochloride hydrate in the form of colorless prism-like crystals.
