diethyl cyclopentane-1,2-dicarboxylate

Conditions: temp:130.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: Load 1 kg of diethyl 1,2-cyclopentanedicarboxylate and 1.02 kg of 27% ammonia into an autoclave. The reaction mixture is heated in the autoclave at a temperature of 130° C. for a minimum of 4 hours. After cooling to 60° C. and depressurisation, evaporation of the solvent is carried out. The residue is then subjected to pyrolysis at 280° C. for 1 hour. The imide is purified by distillation in vacuo (4-12 mbars) at a temperature of 200° C. After isolation, the title product is obtained in a yield of 96%. After cooling to 60° C. depressurisation, evaporation of the solvent The imide is purified by distillation in vacuo (4-12 mbars) at a temperature of 200° C
