Reaction Steps

To a solution of 1-bromo-4-methylpentane (5.0 g, 0.030 mol) in DMF (20 mL) was added potassium phthalimide (5.9 g, 0.032 mol) in one portion at room temperature. After stirring at room temperature of 1 hr, the mixture was heated at 55° C. for 16 hr. Chloroform (30 mL) was added to the reaction mixture and the resulting mixture was poured into water (100 mL). The aqueous phase was extracted with chloroform and the combined organic phase was washed with 0.25 M NaOH (aq) and water. The organic phase was dried (Na2SO4), filtered and concentrated in vacuo to give 2-(4-methylpentyl)-1H-isoindole-1,3(2H)-dione as a pale yellow oil. (M+H) 232, 2.80 min. (LC/MS method A).
