3-Aminophthalimide may be used in direct chemiluminescent cellular bioassays. It may also be used in the preparation of 3-bromopthalimide. | [General Description]
3-Aminophthalimide (API) is a stable precursor of luminol. API can be prepared by the hydrogenation of 3-nitrophthalimide and methanol in the presence of 10% Pd-C. | [Synthesis]
The general procedure for the synthesis of 3-amino phthalimide from 3-nitrophthalimide was as follows: 3-nitrophthalimide (LOOGR) was placed in a hydrogenation reactor and dissolved by adding 500 mL of dimethylformamide (DMF). Subsequently, 20 g of wet Ruanne nickel catalyst was added to the solution. The hydrogenation reaction was started by applying a hydrogen pressure of 20-40 psi at 20-30 °C. After the initial exothermic phase of the reaction, the hydrogen pressure was increased to 40-60 psi and the reaction temperature was raised to 40-50 °C to continue the reaction. After the hydrogen is completely absorbed, a sample is taken and analyzed by thin layer chromatography (TLC) to confirm that the 3-nitrophthalimide has been completely converted. Upon completion of the reaction, the reaction mixture was filtered while hot to remove the catalyst. The filtrate was concentrated under reduced pressure at 60-80 °C to remove the solvent. To the residue was added 500 mL of water and stirred for 20-30 minutes. The product was separated by filtration and dried at 60-70 °C to give a yellow crystalline solid 3-aminophthalimide (80 g, 95% yield). The melting point of the product was 262-264 °C. | [References]
