Reaction Steps
52.08 g (0.33 mol) oxalyl chloride is slowly added dropwise at 20° C. to a suspension of 25.0 g (0.11 mol) of 2,2-diphenylpropionic acid, 100 mL of dichloromethane, and 4 drops of dimethylformamide. It is stirred for 1 hour at 20° C. and 0.5 hour at 50° C. The solvent is distilled off and the residue remaining is used in the next step without any further purification.
