Versuchsvorschrift

A stirred solution of 40 g (0.41 mol) of phosgene in 150 ml of toluene is held at 25° C while a mixture of (52.5 mmol) of 3-amino-4-benzyloxyphenyl 2-pyridyl ketone and 300 ml of toluene is added slowly. The mixture is refluxed for 30 minutes and then is concentrated to give 4-benzyloxy-3-isocyanatophenyl 2-pyridyl ketone.
