Procedure
The synthesis of this compound is carried out as described in Example 3, except that, in Step A, the 1-bromo-4(R)-acetoxy-2-nonyne is replaced by an equimolar amount of 1-acetoxy-1-(3-bromo-1-propynyl)cyclooctane (Example V). The product of Step A is thus ethyl 7-{[3-(1-acetoxycyclooctyl)-2-propynyl]methanesulfonamido}heptanoate. The subsequent steps yield 7-{N-[3-(1-hydroxycyclooctyl)-2-propynyl]methanesulfonamido}heptanoic acid (B) and 7-{N-[3(1-hydroxycyclooctyl)propyl]methanesulfonamido}heptanoic acid (C).
