Procedure
N-(3-(3-bromophenyl)-2,2-dimethylpropyl)-2,2,2-trifluoroacetamide (30) (0.489 g, 1.45 mmol) was coupled with 4-ethynylheptan-4-ol (20) (0.28 g, 2.0 mmol) following the method described in Example 15 and the product was purified by flash chromatography (0 to 50% EtOAc-hexanes gradient) to give 2,2,2-trifluoro-N-(3-(3-(3-hydroxy-3-propylhex-1-ynyl)phenyl)-2,2-dimethylpropyl)acetamide (31) as a yellow oil. Yield (0.350 g, 61%): 1H NMR (400 MHz, CD3OD) δ 7.20-7.25 (m, 3H), 7.12-7.15 (m, 1H), 3.19 (s, 2H), 2.54 (s, 2H), 1.58-1.71 (m, 8H), 0.98 (t, J=7.2 Hz, 6H), 0.85 (s, 6H).
