methyl 1,3-dioxoisoindole-2-carboxylate

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

Procedure: A suspension comprising 25 millimoles of potassium phthalimide and 20 ml of methylchloroformate is refluxed for a period of approximately 31/2 hours. Upon completion of refluxing, the reaction mediuim is cooled, filtered, with insolubles being removed continuously by treatment with hot acteone until only potassium chloride remains. The desired product m.p. 184° - 184.5°C., is obtained from the acetone. is refluxed for a period of approximately 31/2 hours Upon completion of refluxing the reaction mediuim is cooled filtered, with insolubles being removed continuously by treatment with hot acteone until only potassium chloride
