Reaction Steps

(6-Bromo-3-nitro-quinolin-4-yl)-(1,3-dimethyl-1H-pyrazol-4-yl)-amine (Stage A.3, 3.67 g 9.73 mmol) was shacked in MeOH/THF 1:1 (120 ml) under 1.1 bar H2 in presence of Raney nickel (1.50 g) as catalyst for 5 h at rt. The RM was filtered over celite, the catalyst was washed with MeOH/DCM and the solution was evaporated to dryness to give the title compound as a red solid (HPLC tR 2.44 min (Method A); M+H=334; M−H=332 MS-ES)
