Reaction Steps
The title compound was prepared in analogy to the procedures described in Example 14 but stirring the reaction mixture for 16 h at 60° C., using 1-methyl-4-(2-nitro-1H-imidazol-4-ylmethyl)-piperazine (Step 20.1) instead of 2-nitroimidazole in Step 14.3, Raney nickel and MeOH/THF (1:1) instead of palladium on carbon and MeOH in Step 14.2, and 8-(4-methyl-thiophen-3-yl)-quinoxaline-5-carboxylic acid (Example 67) in Step 14.1. Title compound: ESI-MS: 448.0 [M+H]+; tR=3.00 min (System 1); TLC: Rf=0.14 (DCM/MeOH, 9:1).
