4-(2-(1-(tert-Butyldimethylsilyloxy)-7-phenylheptyl)oxazol-5-yl)phenyl acetate. The title compound was prepared from 2-(1-(tert-butyldimethylsilyloxy)-7-phenylheptyl)-5-(tributylstannyl)oxazole (74 mg, 0.112 mmol) and 4-iodophenyl acetate following General Procedure A. Flash chromatography (5-20% EtOAc/hexanes) yielded the title compound as a clear oil (31 mg, 54%): 1H NMR (CDCl3, 600 MHz) δ 7.65 (d, 2H, J=7.8 Hz), 7.27-7.24 (m, 3H), 7.16-7.14 (m, 5H), 4.82 (t, 1H, J=6.0 Hz), 2.58 (t, 2H, J=7.5 Hz), 2.32 (s, 3H), 1.97-1.87 (m, 2H), 1.65-1.60 (m, 2H), 1.45-1.34 (m, 6H), 0.89 (s, 9H), 0.09 (s, 3H), −0.02 (s, 3H); 13C NMR (CDCl3, 150 MHz) δ 170.2, 165.8, 151.4, 151.3, 143.7, 129.2, 129.1, 126.7, 126.4, 126.2, 123.1, 122.4, 69.5, 37.3, 36.8, 32.3, 30.0, 26.6, 26.6, 26.0, 22.1, 19.1, −4.1, −4.2.
