実験手順
In a 100-mL flask, N-cyclohexyl-4-methylaniline (2.00 g, 10.6 mmol) was dissolved in methylene chloride (20 mL) and a solution of bromine (Br2) (1.69 g, 10.6 mmol) dissolved in methylene chloride (16 ml) was injected at 0° C. for 30 minutes. Then, the solution was further stirred for 2 hours, and a 1 N aqueous KOH (20 mL) solution was added. The solution added with the aqueous solution was transferred to a separatory funnel and extracted from methylene chloride (40 mL) twice. Water was removed from the combined organic layer over MgSO4, and filtered with a glass filter. The rotary evaporator was used to remove the solvent, thereby obtaining a residue. The obtained residue was separated by column chromatography to obtain colorless oil (2.67 g, 94%).
