To a solution of [5-cyclobutyl-3-(2,6-dichlorophenyl)-4-isoxazolyl]methanol (150 mg, 0.503 mmol), methyl 6-(4-hydroxyphenyl)-1-naphthalenecarboxylate (140 mg, 0.503 mmol), triphenylphosphine (145 mg, 0.553 mmol) in dichloromethane (1.5 mL) was added diisopropyl azodicarboxylate (0.099 mL, 0.553 mmol) dropwise. The solution was heated in a microwave reactor at 100° C. for 10 minutes. The product was purified by chromatography (silica gel, 0-15% ethyl acetate in hexanes gradient elution) to afford a white solid (0.069 g, 25%). 1H-NMR (DMSO-d6,) δ 8.77 (d, J=9 Hz, 1H), 8.23-8.20 (m, 2H), 8.09 (d, J=9 Hz, 1H), 7.93 (d, J=11 Hz, 1H), 7.70-7.51 (m, 6H), 6.90 (d, J=9 Hz, 2H), 4.83 (s, 2H), 4.00 (quintet, J=9 Hz, 1H), 3.92 (s, 3H), 2.43-2.31 (m, 4H), 2.10-1.92 (m, 2H). APCI-LCMS m/z 558 (M+H)+.
