Procedure

A slurry consisting of 43 grams (0.2 mole) of III and 39.6 grams (0.4 mole) of phosgene in 500 milliliters of benzene was gradually heated to reflux and refluxed for 3 hours. The resulting clear solution was concentrated under reduced pressure to give 38.7 grams (94.5% yield) of IV as a viscous brown liquid.
