실험 절차

A solution of [3-[(2,6-dichlorophenyl)methyl]-5-(1-methylethyl)-4-isoxazolyl]methanol (0.105 g, 0.35 mmol), ethyl 6-(4-hydroxyphenyl)-1-naphthalenecarboxylate (0.102 g, 0.35 mmol), triphenylphosphine (0.092 g, 0.35 mmol) and diisopropyl azodicarboxylate (0.063 mL, 0.35 mmol) in toluene (3.5 mL) was placed in microwave reaction tube and heated to 80° C. for 500 seconds. The solution was concentrated and purified by chromatography (silica gel, hexane to 1:4 ethyl acetate: hexanes) to provide the title compound (0.126 g, 60.9% as 0.2 EtOAc). 1H NMR (DMSO-d6): δ 8.79 (d, J=9 Hz, 1H), 8.28 (d, J=2 Hz, 1H), 8.23 (d, J=8 Hz, 1H), 8.09 (d, J=7 Hz, 1H), 7.98 (dd, J=2, 9 Hz, 1H), 7.81 (d, J=9 Hz, 2H), 7.61 (t, J=8 Hz, 1H), 7.46 (d, J=8 Hz, 2H), 7.32 (t, J=8 Hz, 1H), 7.16 (d, J=9 Hz, 2H), 5.08 (s, 2 H), 4.40 (q, J=7 Hz, 2 H), 4.29 (s, 2 H), 3.34 (septet, J=7 Hz, overlapping H2O 1 H), 1.37 (t, J=7 Hz, 3 H), 1.22 (d, J=7 Hz, 6 H). ESI-LCMS m/z 574 (M+H)+.
