Combined 6-(5-hydroxy-4-(2-methoxypyridin-4-yl)-1H-pyrazol-1-yl)nicotinic acid (30 mg, 0.096 mmol), EDCI (27.6 mg, 0.144 mmol), HOBT (19.47 mg, 0.144 mmol), and DMF (961 μl), then added (tetrahydro-2H-pyran-4-yl)methanamine (17.66 μl, 0.144 mmol) and Hunig's base (68.3 μl, 0.384 mmol) and stirred at room temperature overnight. The reaction mixture was purified via preparative HPLC to give the title compound (32.1 mg, 82%) as a yellow solid. 1H NMR (400 MHz, methanol-d4) δ ppm 1.35 (qd, J=12.38, 4.55 Hz, 2 H) 1.71 (d, J=12.88 Hz, 2 H) 1.84-1.99 (m, 1 H) 3.42 (td, J=11.68, 1.64 Hz, 2 H) 3.95 (d, J=3.28 Hz, 1 H) 3.98 (s, 3 H) 4.19 (s, 3 H) 7.76 (d, J=6.57 Hz, 1 H) 7.84 (s, 1 H) 8.03 (d, J=6.57 Hz, 1 H) 8.28-8.47 (m, 2 H) 8.55 (br. s., 1 H) 8.85 (br. s., 1 H). MS m/z [M+H]+ 410.1.
