Reaktionsschritte

Starting with the (3R,4R)-7-methoxy-3-(4-methoxy-phenyl)-3-methyl-4-(2-propenyl)thiochroman prepared in Example 2 and ethyl 2-(4,4,5,5,5-pentafluoropentyl)-9-decenoate separately prepared from 1-iodo-4,4,5,5,5-pentafluoropentane, diethyl malonate and 1-iodo-7-octene, a procedure analogous to that as shown in Example 2 or 3 was repeated to give 11-[(3R,4R)-7-hydroxy-3-(4-hydroxyphenyl)-3-methylthiochroman-4-yl]-2-(4,4,5,5,5-pentafluoropentyl)undecanoic acid.
