Versuchsvorschrift

A solution of [3-[2-(2,6-dichlorophenyl)ethyl]-5-(1-methylethyl)-4-isoxazolyl]methanol (0.085 g, 0.27 mmol), methyl 6-(4-hydroxyphenyl)-2-naphthalenecarboxylate (0.075 g, 0.27 mmol), triphenyl phosphine (0.071 g, 0.27 mmol) and diisopropyl azodicarboxylate (0.049 mL, 0.27 mmol) in toluene (2.7 mL) was placed in microwave reaction tube and heated to 80° C. for 1000 seconds. The solution was concentrated and the residue dissolved in a solution of ethyl acetate and methanol, filtered and concentrated. The filtrate was purified by chromatography (silica gel, hexane to 3:7 ethyl acetate:hexanes) to provide the title compound (0.038 g, 24.5%). 1H NMR (DMSO-d6): δ 8.62 (s, 1H), 8.25 (s, 1H), 8.18 (d, J=9 Hz, 1H), 8.06 (d, J=9 Hz, 1H), 7.97 (dd, J=1, 9 Hz, 1H), 7.92 (dd, J=2, 9 Hz, 1H), 7.81 (d, J=9 Hz, 2H), 7.42 (d, J=8 Hz, 2H), 7.25 (t, J=8 Hz, 1H), 7.14 (d, J=9 Hz, 2H), 4.99 (s, 2H), 3.90 (s, 3H), 3.35 (septet, J=7 Hz, overlapping H2O 1H), 3.24-3.20 (m, 2H), 2.89-2.85 (m, 2H), 1.25 (d, J=7 Hz, 6H). ESI-LCMS m/z 574 (M+H)+.
