Procedure

To 1 ml of acetic anhydride was added 0.58 g of 2-amino-1,4-bis(4-dimethylaminobutyl)benzene, and the solution was stirred at 50° C. for 2.5 hours. After adding 8 ml of 5% sodium carbonate, the mixture was stirred at a room temperature for 5 hours, alkalized with 10% sodium hydroxide, subjected to salting out and extracted with total 70 ml of chloroform. The extract was washed with a saturated sodium chloride aqueous solution, dried over potassium carbonate, and evaporated under a reduced pressure to obtain 0.56 g of the title compound as a pale brown crystal.
