Reaction Steps

By the procedure of Example 54, but using only 2.3 equivalents of triethylamine, ethyl 1-(5-chloro-2-ethoxyphenyl)-1-hydroxymethanecarboximidate (8.0 g., 0.029 mole) in 300 ml. of tetrahydrofuran was reacted with phosgene. After stirring for 2 hours at room temperature, isolation was also according to Example 54, substituting chloroform for ethyl acetate, resulting in toluene recrystallized 5-(5-chloro-2-ethoxyphenyl)oxazolidine-2,4-dione (2.7 g., m.p. 197°-199° C.).
