Participants

Reaction Steps

The title compound was prepared from 2-(2-(1-(tert-butyldimethylsilyloxy)-7-phenylheptyl)oxazol-5-yl)phenol (44 mg, 0.094 mmol) following General Procedure D. Preparative thin layer chromatography (30% EtOAc) yielded the title compound as a white solid (3.4 mg, 12%): 1H NMR (CDCl3, 500 MHz) δ 7.94-7.93 (m, 1H), 7.82 (br s, 1H), 7.38-7.34 (m, 4H), 7.26-7.25 (m, 3H), 7.12 (t, 1H, J=15.0 Hz), 7.00 (d, 1H, J=8.0 Hz), 3.18 (t, 2H, J=7.5 Hz), 2.69 (t, 2H, J=7.5 Hz), 1.89-1.83 (m, 2H), 1.75-1.69 (m, 2H), 1.54-1.46 (m, 4H); 13C NMR (CDCl3, 125 MHz) δ 188.8, 153.4, 151.7, 143.1, 131.3, 128.8, 128.7, 127.7, 127.5, 126.0, 121.7, 116.9, 114.5, 39.4, 36.3, 31.7, 29.5, 29.4, 24.5; MALDI-FTMS m/z 350.1751 (M+H+, C22H24NO3, requires 350.1751).
