Versuchsvorschrift

A mixture of N-(2-{[7-(benzyloxy)-3-nitroquinolin-4-yl]amino}-1,1-dimethylethyl)-N′-isopropylurea (4.24 g, 9.39 mmol) and 5% platinum on carbon (1.0 g) in acetonitrile (700 mL) was hydrogenated at 30 psi (2.1×105 Pa) overnight on a Parr apparatus. The mixture was filtered through CELITE filter agent, which was subsequently rinsed with acetonitrile and dichloromethane. The filtrate was concentrated under reduced pressure to yield 3.67 g of N-(2-{[3-amino-7-(benzyloxy)quinolin-4-yl]amino}-1,1-dimethylethyl)-N′-isopropylurea as a pale yellow foam that was used without purification.
