Reaction Steps

When the product of Step A was substituted for 5-(3-chloro-4-propoxyphenyl)-3-(3-iodo-4-isopropoxyphenyl)-1,2,4-oxadiazole in Example 36, Step C, the similar procedure afforded the title compound in 87% yield, as white solid. 1H-NMR (CDCl3) 8.47 (d, 1H, J=1.95 Hz); 8.11 (d, 2H, J=8.94 Hz); 8.03 (dd, 1H, J=8.46, 2.01 Hz); 7.07 (d, 2H, J=8.49 Hz); 4.11 (q, 2H, J=6.96, 13.98 Hz); 1.45 (t, 3H, J=6.96 Hz).
