Versuchsvorschrift

To N-Cbz-[2-(3-hydroxyphenylaminocarbonyl)]-L-proline (5.0 mmol) in HOAc (10 mL) was added 30% HBr in acetic acid and the solution stirred for 40 min. The reaction was quenched by addition of 100 mL ethylether, and the resulting precipitate collected and recrystalized from MeOH/Et2O to afford 3.5 mmol 2-(3-hydroxyphenylaminocarbonyl)-L-proline hydrobromide (70%)
