Reaction Conditions

Reaction Steps

5.05 ml of a 1N aqueous sodium hydroxide solution was added to a solution of 1.20 g of ethyl 2-methylthio-3-[4-[2-[[2-[[1-[4-(2-pyridyl)phenyl]ethylidene]aminoxy]ethoxy]phenyl]propionate obtained in Example 17 in 20 ml of ethanol, and the mixture was stirred at 50° C. for 30 minutes. After the reaction, the ethanol was evaporated under reduced pressure, and 5.05 ml of 1N hydrochloric acid was added to the residue thus obtained, followed by extraction of the precipitated product with ethyl acetate. The extract thus obtained was dried over anhydrous magnesium sulfate and evaporated under reduced pressure. The residual powder thus obtained was washed with isopropyl ether to obtain 0.95 g of the desired compound.
