Reaction Steps
3-Aminobenzisoxazole (300 grams) and 2,6-dichlorobenzoyl isocyanate (600 grams) in 50 ml. methylene chloride were stirred at room temperature for one hour. The solvent was then evaporated and the precipitate recrystallized from ethanol. The identity of the product was determined by NMR and IR analysis, yield 500 mg., m.p.=212°-215° C.
