反应详情

To a solution of 2-vinylpyrimidine (1.55 g, 14.6 mmol) in EtOH (15 mL) at room temperature was added AcOH (2.0 mL) and benzylamine (3.14 g, 29.3 mmol) (3.2 mL). The reaction mixture was heated to reflux for 18 h, and concentrated. Diluted with EtOAc, washed with 5 M NaOH (1×), brine (1×), dried over MgSO4, filtered, and concentrated. Purification by flash column chromatography on silica gel (eluted with 2% to 10% MeOH in DCM) gave N-benzyl-2-(pyrimidin-2-yl)ethanamine.
