3-(5-Butylthiophen-2-yl)-5-{4-[(S)-2-fluorodecyloxy]-phenyl}-isoxazole is prepared similar to Example 6, but 3-(5-butylthiophen-2-yl)-5-(4-hydroxyphenyl)-isoxazole is etherified with (S)-2-fluoro-1-decanol by the method of Mitsunobu (diethyl azodicarboxylate/triphenylphosphine in tetrahydrofuran; Synthesis 1981, 1).
