Reaction Steps

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-chloro-4-acetoxy-4-methylnonane (Example R). The product of Step A is thus ethyl 7-[N-(4-acetoxy-4-methylnonyl)-cyanamido]heptanoate. The subsequent steps yield 7-[N-(4-hydroxy-4-methylnonyl)cyanamido]heptanoic acid (B) and 7-[1-(4-hydroxy-4-methylnonyl)ureido]heptanoic acid (C).
