Participants

Reaction Steps

The title compound was prepared from 5-(2-pyridyl)oxazole and 2-(4-(benzyloxy)phenoxy)acetic acid (commercially available) using General Procedure B. Column chromatography (SiO2, 2.5×6 cm, 20-40% EtOAc-hexanes gradient) followed by PTLC (SiO2, 50% EtOAc-hexanes) afforded 11b (35 mg, 0.09 mmol, 10%) as a pale yellow solid: 1H NMR (CDCl3, 500 MHz) 8.70 (app d, 1H, J=4.0 Hz), 8.04 (d, 1H, J=8.1 Hz), 7.86 (td, 1H, J=7.7, 1.5 Hz), 7.55-7.52 (m, 1H), 7.44-7.33 (m, 6H), 6.94-6.89 (m, 4H), 5.45 (s, 2H), 5.03 (s, 2H); ESI-TOF m/z 387.1343 (C23H19N2O4+H+ requires 387.1345).
