Participants

Reaction Steps

This compound is prepared essentially by the method as described in Example 5, Step E, except that the benzyl 7-{2-(3-benzyloxy-4-[4-fluorophenoxy]butyl)-1,1,4-trioxo-3-thiazolidinyl}heptanoate is replaced by 1-benzyloxy-4(S) acetyloxy-2-nonyne and no chromatographic purification is needed. The title compound is obtained as a mobile oil which is used immediately in Step A-6 below.
