実験手順
4-(4-Pyridinylamino)benzoic acid was prepared from 76.6 g of 4-aminobenzoic acid and 63.5 g of 4-chloropyridine in 240 ml of acetic acid, heated at reflux for 6 hours. With a work-up procedure similar to that of Example 33, there was obtained 50 g of product with the m.p. 322°-324° C.(decompn.).
