Reaction Steps

The title compound was prepared in a similar manner as described for Example 149, from 5-(6-carboxy-2,2-dimethyl-2,3-dihydro-benzofuran-4-yloxy)-pyridine-2-carboxylic acid (163b) (111 mg, 0.288 mmol) and 3-amino-1-methyl-pyrazole (56 mg, 0.576 mmol) to give a white solid (112 mg, 80% yield). 1H NMR (400 MHz, CDCl3) δ 10.19 (s, 1 H) 8.98 (s, 1 H) 8.30 (d, J=2.53 Hz, 1 H) 8.22 (d, J=8.59 Hz, 1 H) 7.28-7.38 (m, 2 H) 7.24-7.28 (m, 1 H) 7.07 (d, J=3.03 Hz, 2 H) 6.79 (d, J=2.02 Hz, 1 H) 6.83 (d, J=2.27 Hz, 1 H) 3.84 (s, 3 H) 3.74 (s, 3 H) 2.89 (s, 2 H) 1.49 (s, 6 H); LCMS for C25H25N7O4 m/z 488.20 (M+H+); Anal. Calcd. for C25H25N7O4.0.1 CHCl3: C, 59.50; H, 5.15; N, 19.35. Found: C, 59.77; H, 5.17; N, 18.96.
