反应详情

To a solution of N,N-bis-(2-hydroxyethyl)-2-fluoro-4-hydroxyaniline (2 g) and KOH (0.64 g, 10.0 mmole) in EtOH (13 mL) was added BnBr (1.1 mL, 9.1 mmole) and the reaction mixture stirred at reflux for 3 h. The reaction mixture was cooled, evaporated to in dryness and purified by silica gel chromatography (0-7% MeOH/DCM) to provide N,N-bis-(2-hydroxyethyl)-2-fluoro-4-benzyloxyaniline (2.26 g) as a yellow syrup.
