Procedure
Coupling of N-(3-(3-bromophenyl)-3-hydroxypropyl)-2,2,2-trifluoroacetamide (25) (55.35 g, 169.7 mmol) with 4-ethynylheptan-4-ol (20) (30.13 g, 214.9 mmol) following the method described in Example 1 gave crude 2,2,2-trifluoro-N-(3-hydroxy-3-(3-(3-hydroxy-3-propylhex-1-ynyl)phenyl)propyl)acetamide (26) as a brown oil which was used in the next step without additional purification. Yield (90.32 g, quant.): 1H NMR (400 MHz, DMSO-d6) δ 9.35 (m, 1H), 7.29-7.34 (m, 3H), 7.22-7.26 (m, 1H), 5.39 (d, J=4.4 Hz, 1H), 5.12 (s, 1H), 4.59 (dt, J=8.4, 4.8 Hz, 1H), 3.25 (quint, J=7.6 Hz, 2H), 1.80 (quint, J=8.0 Hz, 2H), 1.44-1.63 (m, 8H), 0.92 (t, J=7.2 Hz, 6H).
