A mixture of 4-(((1R,3S)-2,2-dimethyl-3-(1-(tetrahydro-2H-pyran-2-yl)-1H-1,2,4-triazol-3-yl)cyclobutyl)amino)-2-(methylsulfonyl)pyrimidine-5-carbonitrile (140 mg, crude), 3-(2-aminoethyl)indolin-2-one hydrochloride (80 mg, 0.376 mmol) and DIEA (194 mg, 1.50 mmol) in NMP (2.0 mL) was stirred at 100° C. for 1 h. Th reaction was diluted with water and extracted with ethyl acetate. The combined organic layers were dried over anhydrous sodium sulfate and concentrated to give a crude product, which was dissolved in a solution of hydrochloride in MeOH (2N, 5 mL) and stirred at room temperature for 5 h. The reaction was neutralized with ammonia and concentrated. The residue was purified by standard methods to afford the title compound (33.4 mg, 0.075 mmol, 20% yield for two steps). 1H NMR (400 MHz, DMSO-d6) δ (ppm) 13.49 (brs, 1H), 10.24 (s, 1H), 8.52-7.41 (m, 3H), 7.29 (t, J=7.6 Hz, 1H), 7.25-7.07 (m, 2H), 7.01-6.93 (m, 1H), 6.87-6.82 (m, 1H), 4.41-4.29 (m, 1H), 3.59-3.43 (m, 2H), 3.42-3.25 (m, 1H), 3.10-2.96 (m, 1H), 2.81-2.66 (m, 1H), 2.49-2.34 (m, 1H), 2.16-1.94 (m, 2H), 1.49-1.00 (m, 3H), 0.63-0.62 (m, 3H). MS (ESI) m/z 444.2 [M+H]+.
