Procedure

100 g adipinic acid and 100 ml acetanhydride were refluxed for 5 hours. The solvent was removed at a rotovap and 100 ml acetonitrile were added to the residue and the mixture was kept in a freezer over night. Then the mixture was fritted and the resulting residue was washed with 50 ml acetonitrile and dried.
