Benzoyl isocyanate → HCID 13910502, compound

Participants

Reaction Steps

To a stirred slurry of 399 mg (3.0 mmole) of 2-oxindole in 7 ml of toluene was added 485 mg (3.3 mmole) of benzoyl isocyanate. The mixture was heated under reflux for 2.2 hours and then it was cooled to room temperature. The solid was recovered by filtration and it was then dissolved in ca. 10 ml of hot acetonitrile. The acetonitrile solution was decolorized using activated carbon and then allowed to cool and the precipitate was recovered by filtration. Recrystallization of the precipitate from acetonitrile gave 131 mg of the title compound, mp 183.5°-184.5° C.
