3-Butyn-1-OL → 4-((6-Methoxybenzofuran-2-yl)ethynyl)phenyl acetate

Participants

Reaction Steps

When 4-iodophenyl acetate and 2-ethynyl-6-methoxybenzofuran were substituted for 4-bromo-N-(6,6-dimethylbicyclo[3.1.1]heptan-2-yl)benzene sulphonamide and but-3-yn-1-ol respectively in Example 18, Step B, the similar process afforded the title compound in 56% yield, as creamy paste. 1H-NMR (CDCl3) 7.56 (d, 2H, J=8.67 Hz); 7.41 (d, 1H, J=8.58 Hz); 7.10 (d, 2H, J=8.7 Hz); 6.97 (d, 1H, J=1.92 Hz); 6.9 (s, 1H); 6.88 (bd, 1H, J=8.61 Hz); 3.85 (s, 3H); 2.3 (s, 3H).
