Reaction Steps

This compound is prepared by the series of reactions described in Example 3, except that in Step B an equivalent amount of 1-chloro-4-acetoxyundecane is substituted for 1-bromo-4-acetoxy-2-nonene and the heating period at 90° C. is extended to 28 hours. There is thus obtained in Step B of this example, ethyl 4-{3-[N-(4-acetoxyundecyl)methanesulfonamido]propyl}benzoate. Saponficiation of this ester is STep C yields 4-{3-[N-(4-hydroxyundecyl)methanesulfonamido]propyl}benzoic acid.
