To a solution of chromic anhydride (40 g) in acetic acid (450 ml) was added a solution of nitromesitylene (20 g) in acetic acid (50 ml) at 65-70° C. over 20 min. This reaction mixture was stirred at 65-70° C. for 30 min and isopropyl alcohol (45 ml) was added. This reaction mixture was further stirred at 50° C. for 30 min. Water was added to the reaction mixture to make the total amount 500 ml and the mixture was ice-cooled. The precipitated crystals were collected by filtration to give the title compound (13 g) as pale-green crystals.
