| Product | 2,6-Xylyl isocyanate | HCID 98787 | 76% |
Reaction Steps
7 g (0.05 mole) of 2,6-dimethyl aniline dissolved in 20 ml of toluene are added dropwise to a 20% solution of phosgene in toluene (1.5 equivalents) maintained at 0° in an ice bath. The mixture is then heated at reflux for 3 h. The mixture is concentrated and the residue is distilled under vacuum. B.p.=100°/13 mm Hg. Yield: 76%.
