Reaction Steps

When the product of Step F was substituted for tert-butyl 5-((4-(5-(3,4-diethoxyphenyl)-1,2,4-oxadiazol-3-yl)indolin-1-yl)methyl)-2,2-dimethyl-1,3-dioxan-5-ylcarbamate in Example 34, Step E, the identical process afforded the title compound in 67% yield., as a colourless foam. 1H-NMR (DMSO-d6) 1.36 (broad s, 3H); 2.91 (s, 2H); 3.29 (m, 2H+H2O); 3.55 (tr, 2H, J=8.02 Hz); 4.55 (m, 2H); 6.75-6.79 (m, 2H); 7.14 (tr, 1H, J=7.9 Hz); 7.26 (d, 1H, 7.8 Hz); 7.72 (d, 1H, J=8.5 Hz); 8.02 (d, 1H, J=9.17 Hz); 8.36 (s, 1H).
