Reaction Steps

A solution of tert-butyl 2-{[tert-butyl(dimethyl)silyl]oxy}-3-[(3-nitroquinolin-4-yl)amino]propylcarbamate (110.18 g, 231.16 mmol) in dichloromethane (500 mL) was added to a Parr vessel. The system was purged with nitrogen, and 10% palladium on carbon (14.76 g, 138.7 mnmol) was added. The vessel was placed under hydrogen pressure (30 psi, 2.1×105 Pa) and shaken for four hours. The reaction mixture was filtered, and, the filtrate was passed through a plug of silica gel and concentrated under reduced pressure to provide 103.45 g of tert-butyl 3-[(3-aminoquinolin-4-yl)amino]-2-{[tert-butyl(dimethyl)silyl]oxy}propylcarbamate.
