Reaction Steps

4-(2-(1-(tert-Butyldimethylsilyloxy)-7-phenylheptyl)oxazol-5-yl)benzenesulfonamide. The title compound was prepared from 2-(1-(tert-butyldimethylsilyloxy)-7-phenylheptyl)-5-(tributylstannyl)oxazole (63 mg, 0.095 mmol) and 4-bromobenzenesulfonamide following General Procedure A. Flash chromatography (2-20% EtOAc/hexanes) yielded the title compound as a white solid (41 mg, 82%): 1H NMR (CDCl3, 500 MHz) δ 8.05 (d, 2H, J=8.5 Hz), 7.83 (d, 2H, J=8.5 Hz), 7.49 (s, 1H), 7.36-7.32 (m, 2H), 7.25-7.22 (m, 3H), 5.39 (s, 2H), 4.92 (t, 1H, J=6.0 Hz), 2.67 (t, 2H, J=7.5 Hz), 2.03-1.96 (m, 2H), 1.74-1.67 (m, 2H), 1.46-1.38 (m, 6H), 0.97 (s, 9H), 0.18 (s, 3H), 0.07 (s, 3H); 13C NMR (CDCl3, 125 MHz) δ 166.6, 149.9, 141.7, 132.8, 129.6, 128.8, 128.7, 128.4, 127.6, 126.0, 124.9, 124.5, 69.1, 36.8, 36.3, 31.8, 29.6, 26.1, 26.1, 25.5, 18.6, −4.5, −4.6.
