When tert-butyl 5-ethynyl-2,2-dimethyl-1,3-dioxan-5-ylcarbamate was substituted for 1-octyne and 4-bromo-iodobenzene was substituted for 5-iodo-2-tritylisoindoline in Example 2, Step D, the similar process afforded the title compound in 63% yield, as a pale paste, which solidified on standing. 1H-NMR (CDCl3) 1.43 (s, 2H); 1.46 (s, 9H); 1.48 (s, 3H); 4.00 (d, 2H, J=11.35 Hz); 4.08 (d, 2H, J=11.41 Hz); 5.19 (s, 1H); 7.26 (d, 2H, J=6.74 Hz); 7.41 (d, 2H, J=6.67 Hz).
