Reaction Steps

When product of Step D 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 (obtained as crude via a process as described in Example 36, Step D) in Example 36, Step E, the similar procedure afforded the title compound in 29% yield, as off white solid. 1H NMR (DMSO-d6) 8.49 (d, 1H, J=2.22 Hz); 8.39 (dd, 1H, J=8.91, 2.22 Hz); 8.28 (d, 1H, J=1.41 Hz); 7.93 (dd, 1H, J=8.55, 1.71 Hz); 7.68 (d, 1H, J=8.58 Hz); 7.48 (d, 1H, J=9.06 Hz); 6.89 (s, 1H); 4.78 (b, 2H); 4.22 (t, 2H, J=6.42 Hz); 3.68-3.52 (m, 4H); 1.84-1.73 (m, 2H); 1.0 (t, 3H, J=7.41 Hz).
