Vorschrift

tert-Butyl 4-(5-(3-fluorophenyl)-1H-pyrrolo[2,3-b]pyridin-4-yl)piperazine-1-carboxylate (0.162 g, 0.409 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. The reaction was then concentrated to dryness, dissolved in minimal DCM, and added dropwise to a stirring solution of 1M HCl in ether. The solid product was filtered, washed with ether, and dried to give 5-(3-fluorophenyl)-4-(piperazin-1-yl)-1H-pyrrolo[2,3-b]pyridine (0.116 g, 95.8% yield) as the dihydrochloride salt.
