実験手順
A mixture of 4.4 g of THPA, 5.3 g of 3B and 60 mL of glacial acetic acid was refluxed for 1 hour, then poured into 300 mL of ice water. The resulting mixture was allowed to stand for 10 minutes, then filtered. The collected solid was washed with cold water, dried under reduced pressure and recrystallized from ethyl acetate/hexane, to give N-(3-(allyloxy)-4-chlorophenyl)-3,4,5,6-tetrahydrophthalimide (3C), as yellow crystals, m.p.: 118.5°-120° C.
