Procedure

By the procedure of Example 27, but using 3 rather than 3.2 equivalents of triethylamine, ethyl 1-hydroxy-1-(2-methoxy-6-nitrophenyl)methanecarboximidate hydrochloride (12 g., 0.041 moles) in 400 ml. of tetrahydrofuran was converted to toluene recrystallized 5-(2-methoxy-6-nitrophenyl)oxazolidine-2,4-dione (8.8 g., 86%; m.p. 181°-183° C.; m/e 252).

Workup

  1. customrecrystallized 5-(2-methoxy-6-nitrophenyl)oxazolidine-2,4-dione (8.8 g., 86%; m.p. 181°-183° C.; m/e 252)
