To a solution of 1,3-oxazolidine-2,4-dione (60.7 g, 0.600 mol) and triethylamine (60.7 g, 0.600 mol) in methylene chloride (500 mL) was added triphenylmethyl chloride (167.3 g, 0.600 mol). After 30 minutes, the thick white solid was collected by vacuum filtration, washed with water (2 L) and dried in a vacuum desicator to give the title compound (201.4 g, 96%). A portion was recrystallized from chloroform to give white plates: mp 216°-218° C.
