Reaction Steps

6-Azaindole (5.00 g, 42.3 mmol) was dissolved in DMF (150 mL) under nitrogen and 1-chloro-4-iodo-benzene (12.2 g, 50.8 mmol), N,N′-dimethylethylenediamine (911 uL, 8.46 mmol), K3PO4 (18.9 g, 88.9 mmol) and CuI (806 mg, 4.23 mmol) were added. The reaction mixture was heated at 150° C. for 18 h. The reaction mixture was filtered and the filtrate was concentrated in vacuo. The residue was suspended in 1M aq Na2CO3 (250 mL) and extracted into DCM (2×250 mL). The combined organic fractions were dried (MgSO4) and concentrated in vacuo. The residue was purified by column chromatography to give the title compound as a yellow solid (8.58 g, 88.6%). LCMS (ES+): 229.1 [MH]+. HPLC: Rt 4.48 min, 98.6% purity.
