Procedure

The crude reaction product 2(2-hydroxy-5-acetylphenyl)2H-benzotriazole (2H5A) is then o-acetylated with an acetic anhydride/pyridine mixture, and after reflux, 2(2-acetoxy-5-acetylphenyl)2H-benzotriazole (2A5A) was produced. The 2(2-acetoxy-5-acetylphenyl)2H-benzotriazole (2A5A) is a key intermediate in the process, and in purified form served as the starting material for the two carbinols.
