3-(2-(1-(tert-Butyldimethylsilyloxy)-7-phenylheptyl)oxazol-5-yl)benzamide. The title compound was prepared from 2-(1-(tert-butyldimethylsilyloxy)-7-phenylheptyl)-5-(tributylstannyl)oxazole (72 mg, 0.109 mmol) and 3-bromobenzamide following General Procedure A. Flash chromatography (10-40% EtOAc/hexanes) yielded the title compound as a white solid (52 mg, 96%): 1H NMR (CD3OD, 600 MHz) δ 8.23 (s, 1H), 8.03 (s, 1H), 7.83 (m, 1H), 7.53 (m, 1H), 7.35 (m, 1H), 7.18-7.09 (m, 5H), 3.30 (t, 1H, J=6.0 Hz), 2.53 (t, 2H, J=7.5 Hz), 1.92-1.86 (m, 2H), 1.65-1.55 (m, 2H), 1.34-1.29 (m, 6H), 0.87 (s, 9H), 0.09 (s; 3H), −0.03 (s, 3H); 13C NMR (CD3OD, 150 MHz) δ 166.2, 151.6, 143.3, 136.6, 135.4, 131.3, 130.8, 128.8, 128.7, 126.9, 126.1, 124.0, 122.9, 122.6, 69.2, 36.8, 36.3, 32.0, 29.6, 29.5, 25.7, 25.6, 18.5, −5.3, −5.4.
