Procedure

To a mixture of 3.6 g N,N'-diheptylterephthalamide obtained in Example 1 and 60 ml toluene, was added dropwise 15.6 ml of a 70% solution of bis(2-methoxyethoxy)aluminum hydride in toluene. After heating under reflux for three hours, the reaction mixture was treated with 30 ml of 2.5N aqueous caustic soda solution under ice cooling, and the toluene layer separated was washed with saturated aqueous solution of sodium chloride and dried over a drying agent. Distilling off the solvent from the dried solution gave 3.24 g of N,N'-diheptyl-p-xylylenediamine.
