Reaction Steps
A solution of 72 mg of lithium hydroxide monohydrate and 3 ml of water was added to a solution of 282 mg of ethyl 3-[4-[2-[[1-(4-biphenylyl)ethylidene]aminoxy]ethoxy]phenyl]-2-(phenylamino)propionate obtained in Example 9 in 3 ml of dioxane. The mixture was stirred at 60° C. for one hour. After the reaction, the reaction mixture was concentrated and diluted with water. Then, 1.71 ml of 1N hydrochloric acid was added to the resulting mixture, and the product thus obtained was extracted with a large amount of hot ethyl acetate. The extract was concentrated to about 5 ml, and 229 mg of the desired compound was obtained by filtration.
