Versuchsvorschrift

To a solution of 4-(4-dimethylcarbamoyl-3-fluoro-phenoxy)-2,2-dimethyl-2,3-dihydro-benzofuran-6-carboxylic acid (143a) (80 mg, 0.21 mmol), 3-aminoisoxazole (36 mg, 0.429 mmol) and triethylamine (0.0597 mL, 0.4294 mmol) in 2 mL of DMF was added HATU (163 mg, 0.429 mmol). The mixture was stirred at 50° C. overnight, and purified by reverse phase column chromatography to give a white solid (3.3 mg, 4% yield). 1H NMR (400 MHz, CDCl3) δ 9.23 (s, 1 H) 7.39 (t, J=8.08 Hz, 1 H) 7.27 (s, 1 H) 7.20 (d, J=1.77 Hz, 1 H) 7.13 (d, J=4.55 Hz, 2 H) 6.82 (dd, J=8.59, 2.27 Hz, 1 H) 6.71 (dd, J=10.61, 2.27 Hz, 1 H) 3.16 (s, 3 H) 3.00 (s, 3 H) 2.92 (s, 2 H) 1.51 (s, 6 H); LCMS for C23H22FN3O5 m/z 440.20 (M+H+).
