反应条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: A solution of 3.0 g. (0.02 mole) of p-methoxyphenyl isocyanate in 10 ml. of dry benzene was added dropwise to a stirring solution of 3.2 g. (0.02 mole) of 3-(2-dimethylaminoethoxy)pyrrolidine in 100 ml. of dry benzene under anhydrous conditions. When the addition was complete, the reaction mixture was allowed to stir for 2 hours. The mixture was concentrated under reduced pressure to give 4.9 g. (80%) of product which crystallized upon standing. Recrystallization from benzeneisooctane gave 4.8 g. of solid melting at 92°-94° C. When the addition The mixture was concentrated under reduced pressure to give 4.9 g (80%) of product which crystallized Recrystallization from benzeneisooctane gave 4.8 g

反应条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: A solution of 10.0 g. (0.0402 mole) of 1-benzyl-3-(2-dimethylaminoethoxy)pyrrolidine in ethanol containing 10% palladium on charcoal was shaken at 60° C. in about three atmospheres of hydrogen until the theoretical amount of hydrogen was used. The cooled filtered solution was concentrated at reduced pressure to give a quantitative yield of oily product. The structure was confirmed by its nuclear magnetic resonance spectrum. The cooled filtered solution was concentrated at reduced pressure
