Participants

Reaction Steps

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-ethanesulfonamidoheptanoate (Example P). The product of Step A is thus ethyl 7-[N-(4-acetoxynonyl)ethanesulfonamido]heptanoate. The subsequent step yields 7-[N-(4-hydroxynonyl)ethanesulfonamido]heptanoic acid (B).
