Experimental Synthesis of Bupropion – A round bottom flask (RBF) containing m-chloropropiophenone (1.0 g‚ 5.9 mmol) dissolved in 5.0 mL dichloromethane (DCM) with 0.25 mL of 1.0 M Br2 in DCM was briefly warmed to initiate the bromination reaction. Afterwards‚ the RBF was placed in and ice-water bath and 1.0 M Br2 in DCM (6.0 mL‚ 6.25 mmol) was added dropwise while stirring. DCM was removed from the reaction by rotary evaporation. Next‚ tert-butylamine (5.0 mL‚ 47.6 mmol) and 5.0 mL of N-methylpyrrolidinone
