Procedure

To 4-Chloro-5-azaindole (120 mg, 079 mmol) in 5 ml DMF was added 4-Fluorobenzylbromide (0.120 ml, 0.95 mmol) then add NaH (32 mg, 0.79 mmol) and stir at room temperature overnight. Work up reaction by adding water and EtOAc then extract three times with EtOAc. Pool all organics and wash one time with brine then dry over sodium sulfate, filter and concentrate to dryness. The residue was purified by chromatography over silica gel (eluted with Hexanes/EtOAc 99:1 to 50:50) to provide 100 mg (50%) of product.
