実験手順
A mixture of 4-chloro-1H-pyrrolo[2,3-b]pyridine (1 g, 6.5 mmol), 4-benzyloxyphenol (1.5 g, 7.5 mmol) and Et3N:TFA (1.2 mL) was heated to 150° C. for 96 h. Formation of the compound was monitored by HPLC-mass spec. The crude was directly purified on silica gel without work-up using a Hexanes/EtOAc gradient (100/0 to 0/100) to afford 4-(4-benzyloxy-phenoxy)-1H-pyrrolo[2,3-b]pyridine.
