実験手順
The synthesis of this compound is carried out as described in Example 1 except that, in Step A, the ethyl 7-(methanesulfonamido)heptanoate is replaced by an equimolar amount of ethyl 7-(methanesulfinamido)heptanoate (Example T). The product of Step A is thus ethyl 7-[N-(4-acetoxynonyl)methanesulfinamido]heptanoate. The subsequent step yields 7-[N-(4-hydroxynonyl)methanesulfinamido]heptanoic acid (B).
