実験手順

To a solution of ethyl 6-chloro-7-(4-(6-(2-chlorophenyl)pyridin-2-ylcarbamoyl)phenoxy)chroman-4-carboxylate (0.010 g, 0.0177 mmol) in 3:1 THF/ethanol (1 ml) was added 1M sodium hydroxide (0.0373 ml, 0.0373 mmol), and the reaction was stirred for 16 hours at ambient temperature. The reaction was concentrated and diluted with water. The reaction was acidified with 1M hydrochloric acid and extracted twice with EtOAc. The combined organic layers were dried over anhydrous sodium sulfate, filtered, and concentrated. The crude material was purified by silica gel preparative thin-layer chromatography eluting with 95:5:1 DCM/MeOH/glacial acetic acid to yield the desired compound (0.007 g, 0.0124 mmol, 70.0% yield). MS (apci) m/z=535.1 (M+H).
