PROCEDURE
实验过程
A suspension of 5-(2-fluorophenyl)-3-iodo-1-tosyl-1H-pyrrolo[3,2-b]pyridine (155 mg, 0.315 mmol), tert-butyl 1-(5-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)pyridin-3-yl)piperidin-4-ylcarbamate (222 mg, 0.551 mmol) Pd(PPh3)4 (36.4 mg, 0.031 mmol, Strem) and Na2CO3, 2.0 M (0.315 mL, 0.630 mmol) in Toluene (2 mL) and EtOH (2 mL) was capped, degassed and backfilled with argon. The reaction was heated to 100° C. After 18 h, the reaction was cooled to 23° C., diluted with EtOAc (75 mL) and washed with brine (50 mL), dried over MgSO4, concentrated in vacuo and purified by silica gel chromatography (eluent: 0-4% MeOH/DCM), affording tert-butyl 1-(5-(5-(2-fluorophenyl)-1-tosyl-1H-pyrrolo[3,2-b]pyridin-3-yl)pyridin-3-yl)piperidin-4-ylcarbamate (134 mg, 66%). MS (ESI, pos. ion) m/z: 642.4 (M+1).
