Procedure
N-(3-(3-Bromophenyl)-3-oxopropyl)-2,2,2-trifluoroacetamide (63) was coupled with alkynol 20 following the procedure described in Example 18 except that the reaction was run at 80° C. for 3 h to give 3-amino-1-(3-(3-hydroxy-3-propylhex-1-ynyl)phenyl)propan-1-one as a dark amber oil after purification by flash chromatography (20% EtOAc in hexanes). Yield (28.1 g, 99.6%). 1H NMR (400 MHz, DMSO-d6) δ 9.40 (br. t, 1H), 7.84-7.92 (m, 2H), 7.58-7.63 (m, 1H), 7.50 (t, J=7.6 Hz, 1H), 5.19 (s, 1H), 3.51 (q, J=5.7 Hz, 2H), 3.30 (t, J=6.7 Hz, 2H), 1.40-1.63 (m, 8H), 0.90 (t, J=7.2 Hz, 6H).
