Versuchsvorschrift

To a solution of (S)-(9H-fluoren-9-yl)methyl 1-(8-chloro-1-formylisoquinolin-3-yl)ethylcarbamate (348) (12.0 g, 26.3 mmol, 1.0 eq) in DMF (150 mL), OXONE (30 g, 48.78 mmol, 1.85 eq) was added and the resulting mixture was stirred at RT over night. The mixture was poured into water (600 mL) and then filtered. The solid was dissolved in ethyl acetate (100 mL), and then PE (300 mL) was added dropwise to this solution. The precipitate was collected by filtration to afford (S)-3-(1-(((9H-fluoren-9-yl)methoxy)carbonylamino)ethyl)-8-chloroisoquinoline-1-carboxylic acid (349).
