  Copper-aluminum hydrotalcite catalysts were effectively used in the coupling of aryl chlorides with aliphatic, aromatic, and N(H)-heterocyclic amines to afford the corresponding N-alkylated/arylated amines in excellent yields. The catalyst was quantitatively recovered from the reaction by simple filtration and reused for a number of cycles with almost consistent activity.

  An improvement to the use of DMF as a solvent for the condensation of 2-chlorobenzoic acids with aliphatic primary or secondary amines was described. A number of alkylaminobenzoic acids and dialkylaminobenzoic acids were synthesized in acceptable-to-good yield. The advantages of this procedure include readily available substrates, the use of an inexpensive copper powder without taking any precautions
