実験手順

In a 25 ml rb flask were placed methanesulfonic acid 5-{4-[3-chloro-4-(pyridine-2-ylmethoxy)-phenylamino]-5,8-dihydro-6H-9-thia-1,3,7-triaza-fluoren-7-yl}-5-oxo-pent-3-enyl ester (0.15 g, 0.25 mmol) in DMF (5.0 ml) and to the solution was added cesium carbonate (0.16 g, 0.5 mmol) followed by dimethylamine (0.5 ml of 2M solution in THF) and heated at 50° C. overnight. The yellow solution was purified by HPLC twice to provide 27.5 mg of light brown solid (20.0%). 1H-NMR (DMSO-d6) δ 8.592-8.574 (m, 1H), 8.378 (s, 1H), 8.181 (s, 1H), 7.890-7.847 (m, 1H), 7.781-7.752 (m, 1H), 7.572-7.552 (d, 1H), 7.514-7.492 (m, 1H), 7.372-7.341 (m, 1H), 7.237-7.207 (m, 1H), 5.271 (s, 2H), 4.942-4.761 (m, 2H), 3.922-3.781 (m, 2H), 3.282-3.169 (m, 4H), 2.343 (m, 2H), 2.127-1.977 (m, 8H).
