反应详情

tert-Butyl 4-(5-(2-fluorophenyl)-1H-pyrrolo[2,3-b]pyridin-4-yl)piperazine-1-carboxylate (0.045 g, 0.11 mmol) was placed in DCM (3 mL) at room temperature. TFA (0.3 mL) was then added, and the reaction was stirred at room temperature for 1 hour and concentrated to dryness. The resulting residue was then dissolved in minimal DCM and added to a stirring solution of 1M HCl in ether. The resulting solid was filtered, washed with ether and dried to give 5-(2-fluorophenyl)-4-(piperazin-1-yl)-1H-pyrrolo[2,3-b]pyridine (0.034 g, 81% yield).
