반응 단계
A mixture of 3-nitrophenyl isocyanate (50 mmoles), 2-oxazolidinone (50 mmoles) and anhydrous AlCl3 (40 mg, 0.3 mmole) is heated at 195° C. for 6 hours with stirring. The reaction mixture is dissolved in dichloromethane and the resulting solution is washed with water twice. The dichloromethane solution is dried and evaporated and the residue distilled at reduced pressure. The distillate is recrystallized from hot hexane to give a yield of 33 percent of the desired product, m.p. 158° C-160° C.
