Procedure

The method of Part B of Example 1 was used to hydrogenate tert-butyl 4-{[(2-chloro-3-nitroquinolin-4-yl)amino]methyl}benzylcarbamate (20 g, 45 mmol) with the modification that magnesium sulfate was added to the mixture before filtration. tert-Butyl 4-{[(3-amino-2-chloroquinolin-4-yl)amino]methyl}benzylcarbamate (18 g) was isolated as a thick, orange-red oil.
