Procedure
A 99.0 g amount of 2-(10-bromodecyl)-1H-isoindole-1,3(2H)-dione (prepared as described above) was dissolved in 300 ml of warm N,N-dimethylformamide with stirring. This solution was added to a stirred solution of 1H-imidazole, sodium salt (prepared by stirring a mixture of 20 g of imidazole and 14.0 g 50% sodium hydride in 500 ml of N,N-dimethylformamide at room temperature for 48 hours). The resulting mixture was heated on a steam bath for 14 hours, then taken to dryness in vacuo. The residue was partitioned between 500 ml of dichloromethane and 250 ml of water. The organic layer was washed with 250 ml of water, dried over magnesium sulfate and filter. The filtrate was evaporated in vacuo and gave 85.4 g of 2[10-(1H-imidazol-1-yl)decyl]-1H-isoindole-1,3(2H)dione as an oil which solidified on standing at room temperature.
