Following the procedure of Example 138, ethyl 1-hydroxy-1-(2-methyl-1-naphthyl)methanecarboximidate hydrochloride (0.47 g., 1.9 mmoles) in 30 ml. of tetrahydrofuran was converted to toluene recrystallized 5-(2-methyl-1-naphthyl)oxazolidine-2,4-dione (185 mg., m.p. 145°-147° C., m/e 241). Recrystallization from hexane-ether gave an analytical sample (m.p. 147°-150° C.).
