Reaction Steps
The title compound was prepared in analogy to the procedures described in Example 14 but using 8-(2,6-difluoro-3,5-dimethoxy-phenyl)-quinoxaline-5-carboxylic acid ethyl ester (Step 124.1) and stirring the reaction mixture for 3 h at 70° C. Ethyl-methyl-(2-nitro-1H-imidazol-4-ylmethyl)-amine (Step 157.1) instead of 2-nitroimidazole was used in Step 14.3, and Raney nickel and MeOH/THF (1:1) instead of palladium on carbon and MeOH in Step 14.2. Title compound: ESI-MS: 483.9 [M+H]+; TLC: Rf=0.10 (DCM/MeOH, 9:1).
