3-Nitrophthalimide (LOOGR) was taken into a beaker and dissolved using 200ML of dimethylformamide and 300ML of methanol. The solution was transferred into a 1L hydrogenation kettle and 20gr of Raney nickel was charged into the kettle. Hydrogenation was carried out initially at 20-40psi and 25-30C until the exothermic nature was over. Hydrogenation was further continued at 40-60psi pressure and 40-50C. After checking the completion of reaction by TLC catalyst was removed by filtration and the solvents distilled off from the reaction mixture at 50-60C. The residue thus obtained was suspended in water (500ML) and filtered off to get a bright yellow crystalline compound of 3-aminophthalimide (78gr, 92.5%). Melting point: 263-4C

The basis of chemical reaction formula synthesis, the synthesis route is composed of some specific reactions and combined according to certain logical thinking. We look forward to the emergence of more reaction modes in the future.
