Procedure
Using the method described in Example 66, 3-cyclopentyl-2-[4-(2-fluoro-phenoxy)-6-oxo-6H-pyridazin-1-yl]-propionic acid (Intermediate 43) and 6-amino-nicotinic acid methyl ester afforded 6-{3-cyclopentyl-2-[4-(2-fluoro-phenoxy)-6-oxo-6H-pyridazin-1-yl]-propionylamino}-nicotinic acid methyl ester as a yellow solid (200 mg, 30%); ESI-LRMS m/e calcd for C25H25F N4O5 [M+] 481, found 481 [M+H+]. 1H-NMR (300 MHz, DMSO-d6) δ ppm 1.00-1.21 (m, 1H) 1.26-1.84 (m, 8H) 1.87-2.05 (m, 1H) 2.22-2.40 (m, 1H) 3.86 (s, 3H) 5.58 (dd, J=10.9, 4.2 Hz, 1H) 5.82 (d, J=2.8 Hz, 1H) 7.29-7.56 (m, 4H) 8.10 (d, J=9.0 Hz, 1H) 8.24 (d, J=2.8 Hz, 1H) 8.28 (dd, J=9.0, 2.3 Hz, 1H) 8.87 (d, J=2.3 Hz, 1H) 11.42 (s, 1H).
