Reaction Steps
The 4-chlorophthalic acid N-benzylimide is prepared by refluxing 4-chlorophthalic anhydride (13 g; 71.2 mmol) with 7.63 g (71.2 mmol) of benzylamine in xylene, the water being separated off. After evaporation of the mixture and recrystallisation of the residue from toluene/cyclohexane, 18.01 g (93% of theory) of 4-chlorophthalic acid N-benzylimide are obtained; melting point: 117°-119° C.
