Procedure

A solution of 1-chloro-1,1-diphenylmethane (3.42 g, 16.93 mmol), N-hydroxyphthalimide (2.30 g, 14.11 mmol) and Et3N (3.0 ml) in DMF (50 ml) was stirred at 60° C. under N2 for 8 hours. After the reaction mixture was cooled to room temperature, water (100 ml) was added. The mixture was extracted with Et2O. The combined organic phase was dried over N2SO4. After evaporation of the solvent, the crude product was purified by chromatography (Hexane/Benzene/EtOAc=20/10/3) to give a white solid, 3.95 g (85% yield). 1H NMR (CD3Cl) δ 7.72-7.63 (1H, m), 7.56-7.53 (1H, m), 7.40-7.24 (12H, m), 5.85 (1H, s, Ph2CH).
