実験手順

The title compound was prepared in analogy to the procedure described in Example 115 but using 8-(2-chloro-6-fluoro-3,5-dimethoxy-phenyl)-quinoxaline-5-carboxylic acid ethyl ester (Step 144.1), 5-(4-methyl-piperazin-1-ylmethyl)-pyridin-2-ylamine (Example 31; purified by silica gel column chromatography), 2 equiv of trimethyl aluminum, stirring the reaction mixture for 4 h at 80° C., pouring it onto a saturated aqueous solution of NaHCO3 and DCM. Title compound: ESI-MS: 551.1 [M+H]+; tR=3.50 min (System 1); TLC: Rf=0.20 (DCM/MeOH/NH3aq, 94:5:1).
