N1-((Ethylimino)methylene)-N3,N3-dimethylpropane-1,3-diamine hydrochloride (0.10 g, 0.53 mmol) was added to a solution of (6S)-2′-oxo-1′,2′,5,7-tetrahydrospiro[cyclopenta[b]pyridine-6,3′-pyrrolo[2,3-b]pyridine]-3-carboxylic acid (described in Intermediate 1) (111 mg, 0.39 mmol), (3S,5S,6R)-3-amino-6-methyl-5-(2-methylphenyl)-1-(2,2,2-trifluoroethyl)piperidin-2-one hydrochloride (described in Intermediate 6) (127 mg, 0.38 mmol), 3H-[1,2,3]triazolo[4,5-b]pyridin-3-ol (HOAt, 15 mg, 0.11 mmol), and triethylamine (0.16 mL, 0.91 mmol) in DMF (3 mL), and the resulting mixture was stirred at 23° C. for 18 h. The reaction mixture was then partitioned between saturated aqueous sodium bicarbonate solution (10 mL) and ethyl acetate (2×30 mL). The combined organic layers were washed with brine, dried over sodium sulfate, and concentrated. The residue was purified by flash column chromatography on silica gel, eluting with 1% methanol→7% methanol/dichloromethane to afford the title compound. HRMS: m/z=564.2219 (M+1), calculated m/z=564.2234 for C30H28F3N5O3. 1H NMR (500 MHz, CDCl3) δ 8.91 (s, 1H), 8.56 (s, 1H), 8.17 (dd, 1H, J=5.0, 1.5 Hz), 8.05 (s, 1H), 7.30 (d, 1H, J=5.0 Hz), 7.20 (m, 3H), 7.12 (m, 2H), 6.89 (dd, 1H, J=7.5, 5.0 Hz), 5.00-4.94 (m, 1H), 4.55 (m, 1H), 3.93-3.90 (m, 1H), 3.81-3.76 (m, 2H), 3.68 (d, 1H, J=16.5 Hz), 3.31-3.23 (m, 2H), 3.17 (d, 1H, J=16.5 Hz), 2.75-2.67 (m, 2H), 2.41 (s, 3H), 1.11 (d, 3H, J=6.5 Hz).
