Conditions

Temperature: 80 °C

Procedure

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), N-(6-amino-pyridin-3-ylmethyl)-N,N′,N′-trimethyl-ethane-1,2-diamine (prepared as described in Example 26 but using N,N,N′-trimethyl-ethane-1,2-diamine in Step 26.2 and purified by column chromatography), 2 equiv of trimethyl aluminum, stirring the reaction mixture for 5 h at 80° C., pouring it onto a saturated aqueous solution of NaHCO3 and DCM. The title compound: ESI-MS: 553.1 [M+H]+; tR=3.43 min (System 1); TLC: Rf=0.06 (DCM/MeOH/NH3aq, 94:5:1).
