실험 절차

At room temperature, to a mixture of 3-ethoxy-2-methylaniline 33.0 g and toluene 400 mL was added triphosgene 25 g, and the resulting mixtures were stirred with heating reflux for four hours. The mixtures were concentrated under reduced pressure to give 1-ethoxy-3-isocyanato-2-methylbenzene 37.2 g.
