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), stirring the reaction mixture for 7 h at 70° C., and using dimethyl-(2-nitro-1H-imidazol-4-ylmethyl)-amine (Step 22.1) 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: 468.1 [M+H]+; tR=3.29 min (System 1); TLC: Rf=0.18 (DCM/MeOH/NH3aq, 91.5:7.5:1).
