Reaction Steps

A mixture of 1'-(3,4-dichlorobenzyl)-4-ethoxycarbonyl-spiro[pyrrolidine-3,3'-indoline]-2,2'5-trione(8.2 g.) and acetic acid (50 ml.) was heated under reflux for 22 hours. The solution obtained was cooled and poured into water (300 ml.). The solid which formed was collected by filtration and recrystallised from methanol to give 1'-(3,4-dichlorobenzyl)-spiro[pyrrolidine-3,3'-indoline]-2,2'5-trione (2.3 g.), m.p. 203°-204° C.
