الإجراء التجريبي

A mixture of 1-methoxy-2-methyl-3-aminobenzene 15.0 g, triphosgene 48.7 g and toluene 350 mL was stirred with heating under reflux for three hours. The reaction mixtures after standing to cool were concentrated under reduced pressure to give 1-methoxy-3-isocyanato-2-methylbenzene 17.0 g.
