Reaction Conditions

Reaction Steps

A mixture of 2.4 g (0.007 mol) of 1-(3-nitrophthalimidyl)-7-hydroxynaphthalene and 0.52 g (0.008 mol) of sodium azide in 14 ml of dimethylsulphoxide is stirred for 24 hours at 80° C. 100 ml of water are added to the solution. The crystals which have precipitated are filtered off with suction, washed with water and dried at 80° C./100 mm Hg. 1.7 g (73.6% of theory) of 1-(3-azidophthalimidyl)-7-hydroxynaphthalene are obtained; melting point 154° C. (with decomposition). IR spectrum (KBr): 1775 and 1720 cm-1 (CO--N--CO); 2130 cm-1 (N3).
