Reaction Steps

5-{7-[2-Chloro-4-(4,5-dihydro-2-oxazolyl)phenoxy]heptyl}-3-methylisoxazole [IX; R=CH3, R2, R3, R4, R5 and R6 =H, R1 =2-Cl, Y=(CH2)7, oxazole at 4-position] was prepared from 5-(7-bromoheptyl)-3-methylisoxazole (Example 9, part c) and 4,5-dihydro-2-(3-chloro-4-hydroxyphenyl)oxazole according to the procedure of Example 9, part (d), and was obtained in the form of a colorless solid, m.p. 120°-120.5° C. when recrystallized from methanol and further purified by chromatography.
