4-Nitrobenzamide → 4-nitrobenzoylisocyanate

Participants

Reaction Steps

48 ml of oxalyl chloride were added batchwise to a solution of 50 g of 4-nitrobenzamide in 1.2 l of 1,2-dichloroethane and the reaction mixture was boiled for 17 hours with reflux. For workup, the reaction mixture was concentrated and the remaining residue distilled under a high vacuum. 56 g of 4-nitrobenzoylisocyanate were obtained as colorless crystals.
