Combined (R)-butan-2-amine (22.8 mg, 0.312 mmol) and a solution consisting of 6-(4-(4-cyano-2-methylphenyl)-5-hydroxy-1H-pyrazol-1-yl)nicotinic acid (50 mg, 0.156 mmol), HOBT hydrate (35.9 mg, 0.234 mmol), EDCI (44.9 mg, 0.234 mmol), and Hunig's base (0.103 mL, 0.624 mmol) in DMA (1 mL) and stirred at 50° C. for 4 h. The reaction mixture was then purified via preparative HPLC to give the title compound as a yellow solid. 1H NMR (400 MHz, DMSO-d6) δ ppm 0.90 (t, J=7.45 Hz, 3 H) 1.17 (d, J=6.57 Hz, 3 H) 1.44-1.63 (m, 2 H) 2.44 (s, 3 H) 3.95 (dt, J=14.02, 7.14 Hz, 1 H) 7.57-7.90 (m, 3 H) 7.92-8.73 (m, 4 H) 8.82-8.97 (m, 1 H) 13.20 (br. s., 1 H). MS m/z [M+H]+ 376.
