A convenient method for the synthesis of indoprofen, which is a potent antiinflammatory agent, was described. Ethyl alpha-(4-aminophenyl)propionate was prepared by nitration of ethyl alpha-phenylpropionate, followed by reduction. Ethyl alpha-[4-(1,3-dioxo-2-iso-indolinyl)phenyl]propionate was obtained from condensation reaction of phthalic anhydride and ethyl alpha-(4-aminophenyl)propionate. Indoprofen was prepared by reduction of ethyl alpha-[3-(1,3-dioxo-2-iso-indolinyl)phenyl]propionate with zinc dust-acetic acid, followed by hydrolysis of the resultant ethyl alpha-[4-(l-oxo-2-iso-indolinyl)phenyl]propionate.
