✦ Synopsis

The t i t l e compound was prepared i n three steps w i t h 55% overall y i e l d s t a r t i n g from potassium (lSN)phthal imide. The synthetic rout e involved reaction w i t h 1,2-dibromoethane, hydrolysis of the res u l t i n g N-(2-br0moethyl)(N)phtha7imide w i t h HBr and treatment of the 2-brom0ethyl(N)amine thus formed w i t h sodium sulphite. The product was characterized by 13C, ' H and "N NMR spectroscopy. The absolute coupling constants of I 5 N w i t h the

1 3 C nuclei and the non-exchanging protons were determined and an unambiguous assignment of the proton signals obtained.
