실험 절차
By the procedure of Example 3, except that a reaction time of 16 hours at room temperature was used following cold perfusion with phosgene, ethyl 1-hydroxy-1-phenylmethanecarboximidate hydrochloride (22 g., 0.102 mole) in 450 ml. of tetrahydrofuran was converted to toluene recrystallized 5-phenyloxazolidine-2,4-dione (10.5 g., m.p. 103°-105° C.).
