Trifluoroacetic acid → 3-Methyl-5-phenyl-4-(piperazin-1-yl)-1H-pyrrolo[2,3-b]pyridine

Participants

Reaction Steps

tert-Butyl 4-(3-methyl-5-phenyl-1H-pyrrolo[2,3-b]pyridin-4-yl)piperazine-1-carboxylate (0.390 g, 0.994 mmol) was placed in DCM (10 mL) at room temperature. TFA (1 mL) was 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 3-methyl-5-phenyl-4-(piperazin-1-yl)-1H-pyrrolo[2,3-b]pyridine (0.350 g, 96.4% yield), which was used without further purification.
