実験手順
To a solution of tert-butyl 4-(2,6-dichloropyridin-4-yl)piperidine-1-carboxylate (2 g, 6.06 mmol) in DCM (2 mL) was added TFA (3 mL). The solution was stirred at room temperature for 30 min. The reaction solution was concentrated to afford 2,6-dichloro-4-(piperidin-4-yl)pyridine as TFA salt, which was used without further purification. LCMS (ESI) [MH]+=231.1.
