実験手順

To a mixture of 200 mg of ethyl (4-amino-2-[p-(4-phenylbutoxy)benzamido]phenoxyacetate hydrochloride, 40.5 mg of triethylamine and 5 mg of methylene chloride was added 30 mg of ethyl isocyanate followed by stirring at room temperature overnight. The reaction mixture was treated in a manner similar to Example 68 to obtain 130 mg of ethyl 4-(3-ethylureido)-2-[p-(4-phenylbutoxy)benzamido]phenoxyacetate.
