Reaction Steps
The title compound was prepared in analogy to the procedures described in Example 14 but stirring the reaction mixture for 2 h at 70° C. and using 8-(2,6-difluoro-3,5-dimethoxy-phenyl)quinoxaline-5-carboxylic acid ethyl ester (Step 124.1). 4-(2-Nitro-1H-imidazol-4-ylmethyl)morpholine (Step 23.1) was used instead of 2-nitroimidazole in Step 14.3, and Raney nickel and MeOH/THF (1:1) instead of palladium on carbon and MeOH in Step 14.2. The title compound: ESI-MS: 511.1 [M+H]+; tR=3.21 min (System 1); TLC: Rf=0.34 (DCM/MeOH/NH3aq, 94:5:1).
