Versuchsvorschrift

Manganese dioxide (0.6 g) was added to a solution of (R)-tert-butyl 5-(1-(tert-butyldimethylsilyloxy)-2-(1-(3-(hydroxymethyl)phenyl)-2-methylpropan-2-ylamino)ethyl)-2-oxo-1,2-dihydroquinolin-8-yl carbonate (Example 275, step f) (0.44 g) in dichloromethane (30 mL) and the mixture stirred vigorously at 20° C. for 3 hours. The reaction mixture was filtered through diatomaceous earth and the solvent removed under reduced pressure to afford the subtitled compound. Yield 0.42 g.
