PROCEDURE
实验过程
A vial charged with (S)-2′-amino-3-bromo-5′H-spiro[chromeno[2,3-b]pyridine-5,4′-oxazol]-7-ol (0.250 g, 0.718 mmol), Pd(PPh3)4 (0.083 g, 0.072 mmol), and copper(i) iodide (0.014 g, 0.072 mmol), was treated with 1 mL THF followed by diisopropylamine (1.535 mL, 10.77 mmol). The solution was degassed with argon and 3,3-dimethylbut-1-yne (0.295 g, 3.59 mmol) was added and the vial heated to 80° C. overnight. The reaction mixture was purified directly by column chromatography yielding (S)-2′-amino-3-(3,3-dimethylbut-1-ynyl)-5′H-spiro[chromeno[2,3-b]pyridine-5,4′-oxazol]-7-ol.
