Anhydrides 1, 6 and 10 have been reacted, independently, with aromatic primary amines 2 in solid phase by simple physical grinding of reactants with p-toluenesulphonicacid as a catalyst to yield corresponding open chain derivatives, monoacid monoamides3,7 and 11 respectively. The latter have each been transformed into the corresponding cyclic derivatives, i.e. imides 5, 9 and 13 respectively in solid phase by simple physical grinding of each with K 2CO3, alkylating agent and tetrabutylammoniumbromide as a catalyst with short reaction times. These cyclic imides can also be obtained by physical grinding of each of 3, 7 and 11 with dicyclohexylcarbodimide as a dehydrating agent in solid phase.
