Reaction Steps

2.75 ml of a 1N aqueous sodium hydroxide solution was added to a mixture of 474 mg of ethyl 2-(N,N-diethylamino)-3-[4-[2-[[1-[4-(2-pyridyl)phenyl]ethylidene]aminoxy]ethoxy]phenyl]propionate obtained in Example 7, 5 ml of methanol and 3 ml of dioxane. The resulting mixture was stirred at 50° C. for 18 hours. After the reaction, methanol and dioxane were evaporated under reduced pressure, and then the residue was diluted with water. The pH of the mixture was adjusted to a value of4 by addition of 2.75 ml of 1N hydrochloric acid, and precipitate was collected by filtration. The precipitate was washed with water and isopropyl ether to obtain 440 mg of the desired compound.
