Reaction Steps

The title compound was prepared in analogy to the procedure described in Step 14.1 but using 8-(2,6-difluoro-3,5-dimethoxy-phenyl)-quinoxaline-5-carboxylic acid (Step 88.1), 6-(4-methyl-piperazin-1-ylmethyl)-pyridin-3-ylamine (Step 39.1), and stirring the reaction mixture for 16 h at rt. The crude product was purified by silica gel column chromatography (DCM/MeOH/NH3aq, 94:5:1) followed by trituration in Et2O. Title compound: ESI-MS: 535.1 [M+H]+; tR=3.15 min (System 1); TLC: Rf=0.13 (DCM/MeOH/NH3aq, 94:5:1).
