The synthesis of this compound is carried out as described in Example 1 except that, in Step A, the 1-chloro-4-acetoxynonane is replaced by an equimolar amount of 1-bromo-4-acetoxy-2-nonyne (Example I, Step 3). The product of Step A is thus ethyl 7-[N-(4-acetoxy-2-nonynyl)cyanamido]heptanoate. The subsequent steps yield 7-[N-(4-hydroxy-2-nonynyl)cynamido]heptanoic acid (B), and 7-[1-(4-hydroxy-2-nonynyl)ureido]heptanoic acid (C).
