実験手順

Coupling of 3-(3-(biphenyl-3-ylethynyl)phenyl)propan-1-ol with phthalimide was conducted following the method described in Example 21. Purification by flash chromatography (6% EtOAc-hexanes) gave 2-(3-(3-(biphenyl-3-ylethynyl)phenyl)propyl)isoindoline-1,3-dione. Yield (0.320 g, 42%): 1H NMR (400 MHz, CDCl3) δ 7.84 (dd, J=5.6, 3.2 Hz, 2H), 7.77 (m, 1H), 7.71 (dd, J=5.6, 3.2 Hz, 2H), 7.61-7.63 (m, 2H), 7.32-7.57 (m, 8H), 7.18-7.25 (m, 2H), 3.77 (t, J=7.2 Hz, 2H), 2.70 (t, J=7.2 Hz, 2H), 2.02-2.09 (m, 2H).
