Versuchsvorschrift

To a solution of 4-(2-(5-amino-8-methylbenzo[f][1,7]naphthyridin-2-yl)ethyl)-3-methylbenzoyl chloride (Example 116/Step 2) and triethylamine (2.5 eq.) in ether (0.05 M) was added N1,N1,N2-trimethylethane-1,2-diamine (5.0 eq.). The reaction mixture was stirred for overnight. Then the reaction mixture was diluted with ethyl acetate and water. The two phases were separated, and the aqueous layer was extracted twice with ethyl acetate. The combined organic layers were washed with brine, dried over anhydrous MgSO4, and concentrated en vacuo. The crude material was purified by flash chromatography on a COMBIFLASH® system (ISCO) using 0-80% ethyl acetate in hexane to give 4-(2-(5-amino-8-methylbenzo[f][1,7]naphthyridin-2-yl)ethyl)-N-(2-(dimethylamino)ethyl)-N,3-dimethylbenzamide as a white solid. 1H NMR (CDCl3): δ 8.66 (s, 1H), 8.37 (s, 1H), 8.07 (d, 1H), 7.63 (s, 1H), 7.09-7.30 (m, 4H), 3.90 (br, 2H), 3.01-3.19 (m, 4H), 3.08 (s, 6H), 2.72 (br, 5H), 2.52 (s, 3H), 2.33 (s, 3H). LRMS [M+H]=456.3.
