실험 절차

To a solution of (S)-3-(5,6-dihydro-2H-pyran-3-yl)-1-fluoro-5′,6′-dihydrospiro[chromeno[2,3-c]pyridine-5,4′-[1,3]oxazine]-2′,7-diamine (0.095 g, 0.248 mmol) in DMF (1 mL) were added 5-chloro-2-pyridinecarboxylic acid (0.043 g, 0.273 mmol), 0-(−7-azabenzotriazol-1-yl)-n,′n,′n,′n′-tetramethyluronium pf6 (0.099 g, 0.261 mmol) and Hunig's base (0.086 ml, 0.497 mmol) and the resulting mixture was stirred at rt for 15 h. The mixture was quenched with 5 drops of 2 N HCl and stirred for 1 min followed by the addition of water and extracted with EtOAc. The combined organics were dried over Na2SO4, filtered, concentrated and chromatographed on silica gel using 0-3% MeOH/DCM. The product was repurified by HPLC to afford (S)—N-(2′-amino-3-(5,6-dihydro-2H-pyran-3-yl)-1-fluoro-5′,6′-dihydrospiro[chromeno[2,3-c]pyridine-5,4′-[1,3]oxazin]-7-yl)-5-chloropicolinamide as a white solid (0.0334 g, 0.064 mmol, 25.8% yield). MS m/z=522.0 [M+H]+.
