Versuchsvorschrift
When the product of Step A was substituted for 3-chloro-4-ethoxybenzaldehyde in Example 49, Step A, the identical process afforded the title compound in 86% yield. 1H-NMR (DMSO-d6) 0.98 (tr, 3H, J=7.32 Hz); 1.68-1.79 (m, 2H); 4.06 (tr, 2H, J=6.39 Hz); 7.14 (d, 1H, J=8.7 Hz); 7.87 (dd, 1H, J=2.07, 8.61 Hz); 8.01 (d, 1H, J=2.04 Hz); 11.2 (broad s, 1H).
