ABSTRACT OF THE DISCLOSURE This invention relates to novel compounds of the general formula (I) Image (I) wherein R is selected from the group consisting of hydrogen and a halogen atom; R' is selected from the group consisting of an alkyl radical having 1 to 6 carbon atoms and a benzyl radical; R" is selected from the group consisting of an alkyl radical havina 1 to 6 carbon atoms and a benzyl radical; R' and R" , together, may form an alkylene radical having 2 to 6 carbon atoms, which together with the Image group, may form a hetrocyclic ring; and X is a halogen atom; and processes for preparing same. Such compounds are useful as intermediate compounds for the preparation of compounds which in turn are used as intermediates for preparing Naproxen (trade mark) which is a drug having good anti- phlogistic, analgesic and antipyritic activity.
