Procedure
A solution of 2-amino-2-(4-isopropyl-2-methoxyphenyl)-2H-inden-1,3-dione (0.50 g, 1.62 mmol) in anhydrous THF (10 ml) was added triphosgene (0.21 g, 0.71 mmol) and stirred for 30 min. The reaction mixture was concentrated and was dissolved in methanol (6 mL) and was stirred for 2 hrs and was concentrated to afford the title compound (220 mg, 93%).
