Triphosgene → 1-Difluoromethoxy-3-isocyanato-2-methylbenzene

Participants

Reaction Steps

At room temperature, to a mixture of 3-difluoromethoxy-2-methylaniline 6.4 g and toluene 100 ml was added triphosgene 5.48 g, and the resulting mixture was stirred with heating under reflux for one hour. The reaction mixture was concentrated under reduced pressure to give 1-difluoromethoxy-3-isocyanato-2-methylbenzene 7.36 g.
