Sodium Hydroxide → HCID 54232478, compound

Participants

Reaction Steps

1.30 ml of a 1N aqueous sodium hydroxide solution was added to a solution of 310 mg of ethyl 2-ethoxy-3-[4-[2-[[1-[4-(2-pyridyl)phenyl]ethylidene]aminoxy]ethoxy]phenyl]propionate obtained in Example 1 in 5 ml of ethanol, and the mixture was stirred at room temperature for 1.5 hours. After the reaction, the ethanol was evaporated under reduced pressure, and the pH of the mixture was adjusted to a value of 3 with 1N hydrochloric acid. The reaction mixture thus obtained was extracted with ethyl acetate, and the extract was dried over anhydrous magnesium sulfate and concentrated under reduced pressure. The crystalline crude product thus obtained was washed with isopropyl ether and hexane to obtain 232 mg of the desired compound.
