PROCEDURE
实验过程
A suspension of 5-(2,6-difluorophenyl)-3-iodo-1-tosyl-1H-pyrrolo[3,2-b]pyridine (73 mg, 0.143 mmol) and crude tert-butyl 3-(5-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)pyridin-3-ylamino)piperidine-1-carboxylate (113 mg, 0.279 mmol) in toluene (1.000 mL) and EtOH (1 mL) was treated with Na2CO3, 2.0 M (0.143 mL, 0.286 mmol) and Pd(PPh3)4 (16.53 mg, 0.014 mmol, Strem). The reaction mixture was degassed, backfilled with argon and heated to 100° C. under N2. After 15 h, the reaction was cooled to 23° C., filtered through celite, and purified by silica gel chromatography (eluent: 0.5-10% MeOH/DCM), affording tert-butyl 3-(5-(5-(2,6-difluorophenyl)-1-tosyl-1H-pyrrolo[3,2-b]pyridin-3-yl)pyridin-3-ylamino)piperidine-1-carboxylate (Rf=0.5 in 10% MeOH/DCM, desired product) (33 mg, 35%); along with a byproduct, tert-butyl 3-(5-(5-(2,6-difluorophenyl)-1H-pyrrolo[3,2-b]pyridin-3-yl)pyridin-3-ylamino)piperidine-1-carboxylate (Rf=0.2 in 10% MeOH/DCM, de-tosylated product) (31 mg, 43%). MS (ESI, pos. ion) m/z: 660.3 (M+1)
