Procedure
Similarly, 4-[4-(4-methoxy-phenyl)-3-methyl-isoxazol-5-yl]-6-styryl-benzene-1,3-diol (Example 24) was prepared by boron trichloride deprotection of 5-(2,4-Bis-benzyloxy-5-styryl-phenyl)-4-(4-methoxy-phenyl)-3-methyl-isoxazole (prepared from styryl boronic acid coupling of bromo isoxazole intermediate, Example 3))
