To a solution of (6S,8S)-6-(2,3-difluorophenyl)-3-(2,2,2-trifluoroethyl)-5,6,7,8-tetrahydroimidazo[1,2-a]pyridin-8-amine (7.0 mg, 0.023 mmol) in N,N-dimethylforinamide (105 μL) was added (2R)-2′-oxo-1,1′,2′,3-tetrahydrospiro[indene-2,3′-pyrrolo[2,3-b]pyridine]-5-carboxylic acid (6.5 mg, 0.023 mmol), 1-hydroxy-7-azabenzotriazole (0.3 mg, 2.1 μmol), N-methylmorpholine (2.56 μL, 0.023 mmol) and 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride (4.46 mg, 0.023 mmol). The mixture was stirred 25 min. Water was added, and the mixture was purified by reverse phase chromatography (C-18, 95% water/acetonitrile→15% water/acetonitrile with 0.1% trifluoroacetic acid) giving the title compound (10.5 mg). HRMS 594.1931 (M+1). 1H NMR (500 MHz, DMSO): δ 11.10 (s, 1H); 8.84 (d, J=8.6 Hz, 1H); 8.07 (dd, J=5.3, 1.6 Hz, 1H); 7.83 (s, 1H); 7.79 (d, J=8.0 Hz, 1H); 7.40-7.36 (m, 2H); 7.32-7.28 (m, 2H); 7.22 (dd, J=7.3, 1.6 Hz, 1H); 6.92 (s, 1H); 6.88 (dd, J=7.3, 5.3 Hz, 1H); 4.34 (d, J=7.9 Hz, 1H); 3.80 (t, J=10.3 Hz, 4H); 3.40 (d, J=16.3 Hz, 2H); 3.19 (dd, J=16.4, 3.5 Hz, 2H); 2.33-2.29 (m, 2H).
