Procedure

6-Methoxy-4-(4-(4-phenylphthalazin-1-ylamino)phenoxy)quinolin-7-ol (45 mg, 92 μmol) and cesium carbonate (33 mg, 102 μmol) were combined in DMF (2 Ml) and stirred for 5 min. 1-Bromo-2-methoxyethane (9.6 μl, 204 μmol) was added and the mixture was stirred at RT for 12 hours. DMF was then removed under vacuum overnight. The crude material was purified by silica gel chromatography using 0 to 100% ethyl acetate in hexane to afford the titled product. MS: M+H+=545.
