Procedure
The title compound was prepared in a similar manner as described for Example 144, from 4-(4-dimethylcarbamoyl-3-fluoro-phenoxy)-2,2-dimethyl-2,3-dihydro-benzofuran-6-carboxylic acid (143a) (80 mg, 0.21 mmol) and 6-aminonicotinamide (58.8 mg, 0.429 mmol) to give a brown solid (5 mg, 5% yield). 1H NMR (400 MHz, MeOD.) δ 8.82 (d, J=1.52 Hz, 1 H) 8.14-8.32 (m, 2 H) 7.31-7.44 (m, 1 H) 7.18 (dd, J=8.34, 1.26 Hz, 2 H) 6.80-6.97 (m, 2 H) 3.10 (s, 3 H) 2.98 (s, 3 H) 2.93 (s, 2 H) 1.47 (s, 6 H); LCMS for C26H25FN4O5 m/z 493.20 (M+H+).
