Procedure

There is heated at reflux 61.2 mg of acetic anhydride and 27.6 mg of formic acid for 4 hours and 46 mg of 4-amino-3-hydroxy-N-para-phenoxyphenylpicolin-amide of Example 2 is added, dissolved in 5 ml of tetrahydrofuran. After 8 hours at reflux, the reaction mixture is concentrated and purified by chromatography to give 39 mg of a yellow solid MP 208° C.
