Procedure
When the 1-bromobutane and 3-chloro-4-hydroxybenzaldehyde was substituted for 1-bromopropane and 4-hydroxybenzaldehyde in Example 50, Step A, the identical process afforded the title compound in 86% yield, as light yellow oil. 1H-NMR (CDCl3) 0.98 (tr, 3H); 1.56-1.58 (m, 2H); 1.78-1.88 (m, 2H); 4.1 (tr, 2H, J=6.3 Hz); 6.98 (d, 1H, J=7.17 Hz); 7.71 (dd, 1H, J=2.1, 8., Hz); 7.87 (d, 1H, J=2.1 Hz); 9.81 (s, 1H).
