Participants

Reaction Steps

The starting material used in the above example can be prepared as follows: 34.3 g (0.31 mol) of 4-aminophenol and 59.9 g (0.31 mol) of 3-nitrophthalic anhydride in 600 ml of acetic acid are refluxed for 6 hours and the mixture is then stirred into 3,000 ml of water. The product which has precipitated is washed with water and dried for 24 hours at 70° C./30 mm Hg. 69 g (78% of theory) of 4-(3-nitrophthalimidyl)-phenol are obtained; melting point 202° C. IR spectrum (KBr): 1785 cm-1 and 1725 cm-1 (CO--N--CO); 1550 and 1350 cm-1 (NO2).
