Procedure

24 g (58.4 mmol) of 2-[4-(6-bromo-3-nitro-quinolin-4-ylamino)-phenyl]-2-methyl-propionitrile (Example 1e) is shacked in 300 ml of MeOH-THF (1:1) under 1.1 bar of H2 in the presence of 8.35 g of Raney-Ni for 1 h. After completion of the reaction, the catalyst is filtered off and the filtrate is evaporated to dryness to give the title compound as a yellow foam. ES-MS: 381, 383 (M+H)+, Br pattern; analytical HPLC: tret=3.21 min (Grad 1).
