Synthetic Route of 19500-02-8, These common heterocyclic compound, 19500-02-8, name is 3-Methoxy-2-methylaniline, its traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc, below Introduce a new synthetic route.
The 15.0g of 3-amino-1-methoxy-2-methyl, 48.7g of triphosgene and 350 ml of toluene in a mixture of the heating to reflux with stirring 3 hours. Cooling the reaction mixture, the concentrated under reduced pressure, to obtain 17.0g of 1-methoxy-3-isocyanato-2-methylbenzene (called below 4A).
Statistics shows that 3-Methoxy-2-methylaniline is playing an increasingly important role. we look forward to future research findings about 19500-02-8.
