Reaction Steps

Sonogashira coupling of N-(3-(3-bromophenyl)-3-hydroxypropyl)-2,2,2-trifluoroacetamide (43) with ethynylcycloheptane, followed by flash chromatography (5-40% EtOAc/hexanes gradient), gave N-(3-(3-(cycloheptylethynyl)phenyl)-3-hydroxypropyl)-2,2,2-trifluoroacetamide as an amber oil. Yield (0.507 g, 51%): 1H NMR (400 MHz, CDCl3) δ 7.42 (br s, 1H), 7.34-7.36 (m, 1H), 7.19-7.33 (m, 3H), 4.81 (q, J=4.0 Hz, 1H), 3.48-3.68 (m, 1H), 3.32-3.42 (m, 1H), 2.74-2.82 (m, 1H), 2.48 (br s, 1H), 1.85-2.00 (m, 4H), 1.70-1.80 (m, 4H), 2.46-1.64 (m, 6H).
