Procedure

5-{6-[2-Chloro-4-(4,5-dihydro-2-oxazolyl)phenoxy]hexyl}-3-methylisoxazole [IX; R=CH3, R1 =2-Cl, R2, R3, R4, R5 and R6 =H, Y=(CH2)6, oxazole at 4-position] was prepared from 5-(6-bromohexyl)-3-methylisoxazole (Example 14a) and 4,5-dihydro-2-(3-chloro-4-hydroxyphenyl)oxazole (Example 13b) according to the procedure of Example 9, part (b), and was obtained in the form of a colorless solid, m.p. 64.5°-65.5° C. when recrystallized from etherpentane.
