実験手順

A solution of [3-[2-(2,6-dichlorophenyl)ethyl]-5-(1-methylethyl)-4-isoxazolyl]methanol (0.050 g, 0.16 mmol), methyl 7-(4-hydroxyphenyl)-2-naphthalenecarboxylate (0.045 g, 0.16 mmol), triphenyl phosphine (0.042 g, 0.16 mmol) and diisopropyl azodicarboxylate (0.043 mL, 0.16 mmol) in dichloromethane (1.6 mL) was placed in microwave reaction tube and heated to 80° C. for 20 minutes. The solution was concentrated and the residue was purified by chromatography (silica gel, hexane to 3:7 ethyl acetate:hexanes) to provide the title compound (0.059 g, 64%). 1H NMR (DMSO-d6): δ 8.68 (s, 1H), 8.40 (s, 1H), 8.07-7.93 (m, 4H), 7.80 (d, J=7 Hz, 2H), 7.42 (d, J=8 Hz, 2H), 7.28-7.24 (m, 1H), 7.14 (d, J=7 Hz, 2H), 4.99 (s, 2H), 3.91 (s, 3H), 3.32-3.20 (2 m, overlapping H2O, total 3H), 2.89-2.85 (m, 2H), 1.25 (d, J=7 Hz, 6H). ESI-LCMS m/z 574 (M+H)+.
