Reaction Steps

Combined 6-(4-(4-cyanophenyl)-5-hydroxy-1H-pyrazol-1-yl)nicotinic acid (48 mg, 0.157 mmol), HATU (119 mg, 0.313 mmol) and 1-(methoxymethyl)cyclobutanamine hydrochloride (47.5 mg, 0.313 mmol) in DMF (0.9 mL) then added Hunig's base (0.137 mL, 0.784 mmol) and the reaction mixture was stirred at 20° C. for 1 h. Water (100 uL) was then added and the mixture was heated at 70° C. for 16 h, then diluted with 100 uL DMSO and purified by prep HPLC (ACN/water with formic acid) to give the title compound (25 mg, 39.5% yield) as a yellow solid. 1H NMR (400 MHz, DMSO-d6) δ ppm 1.72-1.95 (m, 2H) 2.10-2.21 (m, 2H) 2.21-2.35 (m, 2H) 3.31 (s, 3H) 3.65 (s, 2H) 7.79 (d, J=8.6 Hz, 2H) 8.14 (d, J=6.1 Hz, 2H) 8.44 (d, J=6.6 Hz, 2H) 8.65 (s, 2H) 8.87-8.95 (m, 1H) 13.55 (br. s., 1H). MS m/z 404 [M+H]+.
