PROCEDURE
实验过程
A mixture of di-tert-butyl (6′-bromo-2′,2′-dimethyldispiro[1,3-oxazole-4,4′-chromene-3′,3″-oxetan]-2-yl)imidodicarbonate (13.8 mg), 3-chloro-5-fluorophenylboronic acid (8.7 mg), Pd(PPh3)4 (2.9 mg) and 1M aqueous Na2CO3 (0.063 mL) in dioxane (0.25 mL) was stirred for 12 hours at 100° C. The mixture was filtered by using Chem Elut cartridges and washed with CHCl3. The filtrate was evaporated. The residue was purified with HPLC (Column: Waters SunFire™ Prep C18 OBD micrometer, 19×100 mm; MeOH/0.1% aqueous HCOOH 11/89 to 95/5(v/v)) and afforded 6′-(3-chloro-5-fluorophenyl)-2′,2′-dimethyldispiro[1,3-oxazole-4,4′-chromene-3′,3″-oxetan]-2-amine (4.6 mg).
