실험 절차

To a solution of 1.13 g of 3,4-dichlorophenylacetic acid in 6 mL of THF was added 0.90 g of 1,1'-carbonyldiimidazole. After 30 minutes a solution of 0.61 g of cis-3a,4,7,7a-tetrahydroisoindoline in 2 mL of THF was added and the mixture was stirred at room temperature overnight. Toluene (50 mL) was added, and the solution was washed successively with 5% hydrochloric acid, water, and 10% aqueous sodium carbonate solution, dried, and concentrated to give 1.50 g of cis-2-(3,4-dichlorophenylacetyl)-3a,4,7,7a-tetrahydroisoindole.
