Reaction Steps

N-(3-Bromophenethyl)-2,2,2-trifluoroacetamide was coupled with alkynol 20 following the procedure described in Example 18 except that the reaction was run for 17 h to give 2,2,2-trifluoro-N-(3-(3-hydroxy-3-propylhex-1-ynyl)phenethyl)-acetamide as a brown oil after purification by flash chromatography (10% to 50% EtOAc in hexanes gradient). Yield (0.975 g, 66%). 1H NMR (400 MHz, CDCl3) δ 7.32 (dt, J=7.8, 1.2 Hz, 1H), 7.24-7.29 (m, 2H), 7.10-7.15 (m, 1H), 6.27 (br.s, 1H), 3.61 (q, J=6.7 Hz, 2H), 2.86 (t, J=7.0 Hz, 2H), 1.95 (s, 1H), 1.66-1.74 (m, 4H), 1.52-1.64 (m, 4H), 0.99 (t, J=7.2 Hz, 6H).
