Procedure

A solution of 55 g (0.5 mole) of thiophenol in 50 ml of dimethylsulfoxide was added dropwise with stirring to 250 ml of dimethylsulfoxide containing 21.5 g (0.55 mole) of sodamide. After stirring the mixture at 40° C. for 1 hr, 120 g (0.05 mole) of 3-bromo-1-benzyl-pyrrolidine (slightly exothermic) was added dropwise. The solution was stirred at 60° C. for 1 hr, diluted with 500 ml of water and extracted with isopropyl ether. The ether phase was dried over sodium sulfate and concentrated, and the residue distilled, b.p. 170°-170° C./5 mm. to give 98 g (73%) of product.
