Reaction Steps

To a sealed tube was added (4-Chloro-6-phenyl-[1,3,5]triazin-2-yl)-(5-cyclopropyl-2H-pyrazol-3-yl)-amine (50 mg, 0.16 mmol) and 6-amino-3-oxo-2,3-dihydro-indazole-1-carboxylic acid tert-butyl ester (80 mg, 0.32 mmol) in 1 ml of n-butanol. The contents were heated to 85° C. for 3 hours. The reaction was concentrated in vacuo to give a white solid that was dissolved in 3 ml of dichloromethane and 1 ml of trifluoro acetic acid and stirred for 5 hours at room temperature. The reaction concentrated and the crude residue purified by prep HPLC to afford 34 mg of the desired product as a light yellow solid (39.4% yield). 1H-NMR(DMSO-d6, 500 mHz) δ 10.95 (m, 1H), 10.30 (m, 1H), 9.91 (s, 1H), 8.32 (m, 2H), 8.04 (m,1H), 7.49 (m,4H), 7.25 (m, 1H), 6.14 (s br, 1H), 1.85 (s, 1H), 0.87 (s, 2H), 0.67 (s, 2H).
