Procedure

A solution of [2-(3-{(R)-2-[(R)-2-(8-benzyloxy-2-oxo-1,2-dihydroquinolin-5-yl)-2-(tert-butyldimethylsilanyloxy)ethylamino]propyl}phenyl)ethyl]carbamic acid tert-butyl ester (2.8 g) in 20% trifluoroacetic acid in DCM was stirred at room temperature for 3 h. Saturated aqueous sodium bicarbonate solution was added to neutralize the TFA and the layers were separated. The organic layer was dried over sodium sulfate, filtered and concentrated under reduced pressure to give the title compound, which was used without further purification.
