HCID 52721595-Oxazolemethanol, 4,5-dihydro-2-(4-((7-(3-methyl-5-isoxazolyl)heptyl)oxy)phenyl)-Yield 45%

Procedure

5-{7-[4-(4,5-Dihydro-2-oxazolyl)-2-methylphenoxy]heptyl}-3-methylisoxazole [IX; R=CH3, R2, R3, R4, R5 and R6 =H, R1 =2-CH3, Y=(CH2)7, oxazole at 4-position] was prepared from 4,5-dihydro-2-(4-hydroxy-3-methylphenyl)oxazole and 5-(7-bromoheptyl)-3-methylisoxazole according to the procedure of Example 9, part (d), and was obtained in 45% yield as a light-tan solid, m.p. 90°-92° C., when recrystallized first from methanol and then from tertiary-butyl methyl ether.
