実験手順

Triethylamine (192 mg, 1.9 mmol) was added to a suspension of 3-(4-bromophenyl)pyrrolidine hydrochloride (200 mg, 0.76 mmol) in anhydrous THF (5 mL). The reaction mixture was stirred at room temperature for 5 minutes and treated with methanesulfonyl chloride (100 mg, 0.84 mmol). After the reaction mixture was stirred at room temperature for 20 hours, the mixture was diluted with water and extracted with EtOAc (2×20 mL). The combined organic layers were washed with brine, dried over Na2SO4 and concentrated in vacuo to give 3-(4-bromophenyl)-1-(methylsulfonyl)pyrrolidine (0.25 g, quantitative yield) as a solid which was used for next step directly. MS (ES+) 303.9, 305.9 (79Br M+H, 81Br M+H)+
