Reaction Steps

When the product of Step G was substituted for tert-butyl 2,2-dimethyl-5-((4-octylphenylamino)methyl)-1,3-dioxan-5-ylcarbamate in Example 1, Step B, the identical process afforded the title compound in 67% yield, as a creamy solid. 1H-NMR (CDCl3) 1.54 (broad s, 4H+H2O); 3.07 (m, 2H); 3.19 (s, 2H); 3.47 (s, 2H); 3.55-3.62 (m, 6H); 3.98 (s, 3H); 6.67 (m, 1H); 7.03 (m, 1H); 7.82-7.9 (m, 2H); 8.01-8.06 (m, 1H); 8.22 (s, 1H); 1H-NMR (DMSO-d6) 1.52 (m, 2H); 2.9-3.03 (m, 4H); 3.57 (tr, 2H, J=8.6 Hz); 3.95 (s, 3H); 4.6 (s, 2H); 6.66 (d, 1H, J=8.4 Hz); 7.36 (d, 1H, J=8.4 Hz); 7.62-7.7 (m, 2H); 8.05-8.11 (m, 2H).
