4-chloro-1-isocyanato-2-methylbenzene

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: To a solution of isoindoline (238 mg, 2.0 mmol) in dry 1,4-dioxane (10 mL) was added 4-chloro-2-methylphenyl isocyanate (335 mg, 2.0 mmol) under argon at room temperature.
