Participants

Reaction Steps

Coupling of 3-isopropyl-4-methylpent-1-yn-3-ol with bromide 3 following the coupling method described in Example 17 gave 2,2,2-trifluoro-N-(3-(3-(3-hydroxy-3-isopropyl-4-methylpent-1-ynyl)phenyl)propyl)acetamide as a pale yellow oil. Yield (1.375 g, 66%): 1H NMR (400 MHz, DMSO-d6) δ 9.40 (br s, 1H), 7.26 (t, J=7.6 Hz, 1H), 7.17-7.22 (m, 3H), 4.81 (s, 1H), 3.17 (q, J=6.8 Hz, 2H), 2.56 (t, J=8.0 Hz, 2H), 1.86 (quint, J=6.8 Hz, 2H), 1.76 (quint, J=7.6 Hz, 2H), 0.99 (d, J=6.8 Hz, 6H), 0.94 (d, J=6.8 Hz, 6H).
