Phosgene → Benzyl(butyl)carbamyl chloride

Participants

Reaction Steps

A solution of 20.0 g of phosgene in 100 ml. of toluene is stirred at 0° C. while a solution of 32.6 g. of N-benzyl-n-butylamine in 50 ml. of toluene is added during 15 minutes. The mixture is filtered and the filtrate is evpaorated. The residue is evaporatively distilled at 105° C. under reduced pressure (250-350 microns) to yield N-benzyl-N-(n-butyl)carbamyl chloride as a colorless liquid.
