PROCEDURE
实验过程
A flask was charged with tetrakis(triphenylphosphine)palladium (29.3 mg, 0.025 mmol), 2-(3,6-dihydro-2H-pyran-4-yl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane (106 mg, 0.506 mmol), (S)-2-amino-5′-fluoro-2′-(2-fluoropyridin-3-yl)-5H-spiro[oxazole-4,9′-xanthene]-7′-yl trifluoromethanesulfonate (130 mg, 0.253 mmol), sodium carbonate (saturated) (0.253 mL, 1.266 mmol) and DMF (2 ml). The solution was heated at 85° C. for 18 hours. The product was purified via Gilson HPLC (gradient elution 20-90% MeCN/H2O, 0.1% TFA) to afford (S)-2′-(3,6-dihydro-2H-pyran-4-yl)-4′-fluoro-7′-(2-fluoropyridin-3-yl)-5H-spiro[oxazole-4,9′-xanthen]-2-amine.
