Reaction Steps

When the product of Step F was substituted for tert-butyl 5-(5-(5-(3-chloro-4-propoxyphenyl)-1,2,4-oxadiazol-3-yl)benzofuran-2-yl)-2,2-dimethyl-1,3-dioxan-5-ylcarbamate in Example 36, Step E, the similar procedure afforded the title compound in 26% yield, as creamy green solid. 1H-NMR (CD3OD) 8.39 (d, 1H, J=1.74 Hz); 8.08 (dd, 1H, J=8.73, 1.89 Hz); 7.68 (b, 1H); 7.63 (d, 1H, J=8.73 Hz); 7.58 (d, 1H, J=8.7 Hz); 7.14 (d, 1H, J=1.8 Hz); 7.03 (s, 1H); 6.92 (dd, 1H, J=8.7, 2.22 Hz); 3.98 (d, 2H, J=11.00 Hz); 3.88 (d, 2H, J=11.01 Hz); 3.85 (s, 3H).
