To a solution of 2-bromo-3-((4-fluorophenyl)ethynyi)-6-methoxypyridine (1ntermediate 44, 531mg. 0867 mmol) in anhydrous toluene (9 rnL) was added XPhos (83 mg, 0.17 mmol), Pd2(dba)3(79 trig, 0088 mrnol), and potassium tert-butoxide (292 mg, 260 mmol). After 10 mimi. tert-butyi5-amino-i H-indole- I -carhoxylate (Intermediate ii, 201 trig. 0.867 mmnol) was added. The resultingsolution was refiuxed at 100 O(? for 3hr, then allowed to cool to 20 ¡ãC. The reaction was partitioned between EtOAc and water. The organic phase was separated, dried (MgSO4), filtered, and concentrated in vacuo, no deprotection necessary. Purification (FCC, Si02, 0percent to 30percent EtOAc/ heptanes) afforded the title compound (60 mg, 19percent) as a yellow solid.
