Participants

Reaction Steps

To a solution of ethyl 6-chloro-7-(4-(6-p-tolylpyridin-2-ylcarbamoyl)phenoxy)chroman-4-carboxylate (0.049 g, 0.090 mmol) in 3:1 THF/ethanol (1 ml) was added 1M sodium hydroxide (0.19 ml, 0.19 mmol), and the reaction was stirred at ambient temperature for 16 hours. The reaction was concentrated to dryness and acidified with 1M hydrochloric acid. The reaction was diluted with water and extracted twice with EtOAc. The combined organic layers were dried over anhydrous sodium sulfate, filtered, and concentrated to yield the desired compound (0.035 g, 0.068 mmol, 75% yield). MS (apci) m/z=515.1 (M+H).
