実験手順
To a solution of N-phenylpyrrolidine (73.8 g, 0.501 moL) in tetrahydrofuran (500 mL) was added N-bromosuccinimide (124.8 g, 1.4 equivalents) at 20° C. to 30° C., and the mixture was stirred at the same temperature for 4 hr. 1 mol/L Aqueous sodium hydroxide solution (300 mL) was added to the mixture at 27° C., and the mixture was partitioned. The organic layer was dried over anhydrous magnesium sulfate and filtered naturally, and the filtrate was concentrated under reduced pressure. The residue was recrystallized from methanol to give the title compound (97.4 g, brown crystals). yield 86%. melting point 88.1° C.
