When 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 was replaced with the product of Step C the similar procedure as described in Example 36, Step E gave the title compound (0.008 g, 38%) as light yellow solid. 1H NMR (CD3OD) 7.74 (d, 1H, J=8.28 Hz); 7.6 (s, 1H); 7.4 (s, 1H); 7.2 (dd, 2H, J=8.34, 1.59 Hz); 4.0 (d, 2H, J=11.46 Hz); 3.94 (d, 2H, J=11.46 Hz); 2.7 (t, 2H, J=7.53 Hz); 1.64 (b, 2H); 1.34-1.26 (b, 10H); 0.85 (t, 3H, J=4.8 Hz).
