PROCEDURE

实验过程

A solution of 5-chloro-1-(p-tolylsulfonyl)-3-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)pyrrolo[2,3-b]pyridine (2.41 g, 5.60 mmol) and tert-butyl (3S)-3-[(2-chloro-5-fluoro-pyrimidin-4-yl)amino]pyrrolidine-1-carboxylate, 7a, (1.69 g, 5.30 mmol) in DME (34 mL) and 2M Na2CO3 (8.5 mL) was degassed with nitrogen (5 min) then treated with Pd(PPh3)4 (0.31 g, 0.27 mmol) then heated at 90° C. overnight. The resulting dark solution was filtered through florisil, washed with EtOAc then concentrated in vacuo. The resulting residue was purified by silica-gel chromatography (0-100%) petroleum ether: EtOAc gradient. Removal of the solvent under reduced pressure afforded 1.33 g (42% yield) of a white solid after vacuum drying.
