Versuchsvorschrift
Coupling of 3,5-dimethylhex-1-yn-3-ol with bromide 3 following the method described in Example 2 (except that the alkynol was added after degassing) gave 2,2,2-trifluoro-N-(3-(3-(3-hydroxy-3,5-dimethylhex-1-ynyl)phenyl)propyl)acetamide as a brown oil. Yield (0.287 g, 40%): 1H NMR (400 MHz, DMSO-d6) δ 9.41 (br s, 1H), 7.26 (t, J=7.6 Hz, 1H), 7.16-7.20 (m, 3H), 5.25 (s, 1H), 3.16 (q, J=6.8 Hz, 2H), 2.56 (t, J=7.2 Hz, 2H), 1.90-1.96 (m, 1H), 1.76 (quint, J=7.6 Hz, 2H), 1.53 (m, 2H), 1.42 (s, 3H), 0.96 (d, J=6.8 Hz, 6H).
