Reaction Steps
Starting with the ethyl 2-(3,3,4,4,5,5,6,6,6-nonafluorohexyl)-8-nonenoate prepared from diethyl malonate, 7-iodo-1-heptene and 1-iodo-3,3,4,4,5,5,6,6,6-nonafluorohexane as in Example 9 and the allyl compound prepared in Example 21, the same procedure as shown in Example 21 was repeated to give 10-[(3RS,4RS)-3-ethyl-7-hydroxy-3-(4-hydroxyphenyl)chroman-4-yl]-2-(3,3,4,4,5,5,6,6,6-nonafluorohexyl)decanoic acid.
