Reaction Steps

A mixture of 6-chloro-2-(4-(methylsulfonyl)phenylamino)nicotinamide (30 mg, 0.092 mmol), 3-phenyl-1-oxa-2,7-diazaspiro[4.5]dec-2-ene TFA salt (30.4 mg, 0.092 mmol) and N,N-diisopropylethylamine (0.064 mL, 0.368 mmol) in DMF (1 mL) was stirred at 120° C. for 20 h. The mixture was cooled to room temperature and purified by reverse phase HPLC, using Sunfire S10 30×250 mm column and eluting with 40% to 100% solvent B (10% MeOH-90% H2O-0.1% TFA) in solvent A (90% MeOH-10% H2O-0.1% TFA), to give a brown solid (12 mg, 21%). LCMS: (M+H)+=506.10. 1H NMR (400 MHz, acetonitrile-d3) δ ppm 7.69-7.80 (3H, m), 7.62-7.69 (2H, m), 7.55 (2H, d, J=9.03 Hz), 7.36-7.44 (3H, m), 6.28 (1H, d, J=9.04 Hz), 3.50-3.95 (4H, m), 3.08-3.38 (2H, m), 2.85 (3H, s), 2.01-2.13 (2H, m), 1.65-1.83 (2H, m).
