実験手順

The synthesis of this compound is carried out as described in Example 8 except that, in Step A, the ethyl 7-bromo-2-methylheptanoate is replaced by an equimolar amount of methyl 2,2-dimethyl-7-iodoheptanoate. The product of Step A is thus methyl 7-{N-[4-(2-tetrahydropyranyloxy)nonyl]methanesulfonamido}-2,2-dimethylheptanoate. The subsequent step yields 7-[N-(4-hydroxynonyl)methanesulfonamido]-2,2-dimethylheptanoic acid (B).
