Reaction Steps

A solution of 20.6 g (0.139 mole) of phthalic anhydride, 20 g (0.126 mole) of 5-chloropentylamine hydrochloride and 17.6 ml (0.126 mole) of triethylamine in 250 ml of toluene was heated to 130° C. for 4 hours. The obtained mixture was evaporated to dryness. The residue was taken up into 200 ml of water and extracted with ethyl acetate. The phases were separated and the organic phase was dried over sodium sulfate and evaporated to dryness. From the crude product, 23 g of the title product were obtained as an oil having the following characteristics:
