Procedure

3-Bromocycloheptene (1.75 g) was added dropwise at room temperature to a DMF suspension (10 ml) of sodium succinimide prepared from succinimide (0.99 g) and 60% sodium hydride (0.40 g). This mixture was stirred at room temperature for 24 hours, poured into water (10 ml) and extracted with ether. The oily product obtained by concentration was purified by chromatography on silica gel to obtain 0.09 g of N-(2-cycloheptenyl)succinimide [Compound (214)].
