Procedure

By the procedure of Example 3, except that a reaction time of 2 hours at room temperature was employed following the phosgene perfusion step, ethyl 1-(2-fluorophenyl)-1-hydroxymethanecarboximidate hydrochloride (14.5 g., 0.062 mole) in 500 ml. of tetrahydrofuran was converted to toluene recrystallized 5-(2-fluorophenyl)oxazolidine-2,4-dione (7.32 g., 60%; m.p. 129°-131° C.).
