Application of 262298-02-2,Some common heterocyclic compound, 262298-02-2, name is 4-Methoxy-2-methylphenylacetonitrile, molecular formula is C10H11NO, 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.
Reference example 2 1-cyano-1-(2-methyl-4-methoxyphenyl)propan-2-one Under argon atmosphere, to a solution of the compound prepared in reference example 1 (11.7 g) in ethyl acetate (60 ml), metallic sodium (2.3 g) was added in numbers. The mixture was stirred for 2 hours at 50 §C. Ethyl acetate (40 ml) was added to the reaction mixture, and the mixture was refluxed for 2.5 hours and then it was stirred overnight at room temperature. A precipitation matter was collected by filtration, and it was washed with diethyl ether. The obtained crystal was dissolved into water (300 ml). The solution was adjusted pH 4 by adding 2N hydrochloric acid, and extracted with ethyl acetate. The organic layer was dried over anhydrous sodium sulfate and concentrated to give the title compound (12.06 g) having the following physical data. TLC: Rf 0.45 (n-hexane: ethyl acetate = 1: 1).
These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route 4-Methoxy-2-methylphenylacetonitrile, its application will become more common.
