Reaction Steps

While carbon tetrachloride was refluxed, fuming sulfuric acid was added dropwise to evolve phosgene. When the atmosphere in the apparatus was replaced sufficiently with phosgene, a 4-t-butylaniline toluene solution (containing 6.00 g of 4-t-butylaniline in 250 ml of toluene) was added dropwise and the temperature was gradually elevated to allow the reaction to proceed while the toluene was refluxed. Yield: 5.61 g (79.6%).
