108.3 g (1.05 mol; 1.05 eq) of acetic anhydride are diluted in 370 ml of dichloromethane at 20° C. The solution obtained is cooled to 0±2° C. before introducing 2.8 ml of a 96% sulphuric acid solution in a time of about 10 minutes. After stirring for about 10 minutes, 184.2 g (1 mol, 1 eq) of benzhydrol are introduced in portions at 0° C.±2° C. in 60±15 minutes. The reaction medium is maintained in contact for 2 hours at this temperature.
