Participants

Reaction Steps

1-(1-methylethyl)-6-(4-morpholinylsulfonyl)-1H-indazole-4-carboxylic acid (90 mg, 0.255 mmol), 3-(aminomethyl)-4,6-dimethyl-2(1H)-pyridinone (62.5 mg, 0.331 mmol), 1-hydroxy-7-azabenzotriazole (69.3 mg, 0.509 mmol), EDC (98 mg, 0.509 mmol) and N-methylmorpholine (0.112 mL, 1.019 mmol) were added to Dimethyl Sulfoxide (DMSO) (10 mL) and stirred at room temperature for 16 hours. Next added 40 mL of water and stirred for 10 minutes. The contents were extracted with DCM (5×30 mL), washed with water, dried (MgSO4), filtered, and concentrated in vacuo. The residue was purified via chromatography (eluent: 0% to 100% gradient Hex:EtOAc then 0 to 10% MeOH:EtOAc). The product was collected as 110 mg (88%). 1H NMR (400 MHz, DMSO-d6) δ ppm 1.50 (d, 6H), 2.13 (s, 3H), 2.23 (s, 3H), 2.89-3.05 (m, 4H), 3.54-3.71 (m, 4H), 4.38 (d, J=4.80 Hz, 2H), 5.27 (dt, J=13.07, 6.47 Hz, 1H), 5.90 (s, 1H), 7.80 (d, J=1.01 Hz, 1H), 8.29 (s, 1H), 8.52 (s, 1H), 8.88 (t, J=5.05 Hz, 1H), 11.56 (br. s., 1H); LCMS(ES) [M+H]+488.3
