Versuchsvorschrift

When tert-butyl-5-ethynyl-2,2-dimethyl-1,3-dioxan-5-yl-carbamate was substituted for 1-octyne and 1,4 diiodobenzene was substituted for 5-iodo-2-tritylisoindoline in Example 2, Step D, the similar process afforded the title compound in 34% yield, as the pale solid. 1H-NMR (CDCl3) 1.43 (s, 3H); 1.46 (s, 9H); 1.48 (s, 3H); 2.40 (s, 1H); 3.99 (d, 2H, J=11.34 Hz); 4.00 (d, 2H, J=11.37 Hz); 5.18 (broad s, 1H); 7.12 (d, 2H, J=8.28 Hz); 7.61 (d, 2H, J=8.28 Hz).
