実験手順
To a clear solution of tert-butyl 4-(3-chloropyridin-2-yl)piperazine-1-carboxylate in anhydrous dichloromethane (25 mL) was added TFA (25 mL) dropwise. The yellow solution was stirred at room temperature for 2.5 hour. Reaction was complete as determined by TLC. TFA was azeotropped with dichloroethane to give 1-(3-chloropyridin-2-yl)piperazine in quantitative yield (1.265 g).
