Procedure
To a solution of 200 ml of 2M phosgene in benzene, stirred under nitrogen gas, was added 96 g (0.3 mole) of 1-benzyl-3-(2,3-dichlorophenoxy)pyrrolidine in 300 ml of benzene. The reaction mixture was allowed to stir overnight and then concentrated to an oil. The oil was triturated with 30/60 petroleum ether to give an oil. Solid product, 89 g, was obtained containing a trace of benzyl chloride. The yield was nearly quantitative.
