The reaction was stirred for one hour after the addition was complete. TLC analysis (80:18:2 hexane-diethyl ether-acetic acid) indicated complete reaction. The reaction mixture was poured into hexane, filtered and concentrated to dryness. Recrystallisation from ethanol yielded succinimidyl nervonate as a white solid.
