Related Products of 6306-60-1,Some common heterocyclic compound, 6306-60-1, name is 2-(2,4-Dichlorophenyl)acetonitrile, molecular formula is C8H5Cl2N, 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.
Preparation of alpha-(2,4-dichlorophenyl)-alpha-hydroxymethylene acetonitrile 0.6 g of metal sodium was added to dry ethanol to obtain an ethanol solution of sodium ethoxide. Then, a mixed liquid comprising 37.2 g of 2,4-dichlorophenyl acetonitrile and 22.2 g of ethyl formate, was added thereto under heating to 70 C. After the addition, the mixture was further heated and refluxed for 2 hours and then, left to stand for 1 day. The reaction solution was cooled to 0 C. and then subjected to filtration. After washing with diethyl ether, the sodium salt collected by filtration was added to 130 ml of distilled water, and 9 ml of acetic acid was dropwise added thereto under cooling at 0 C. After the dropwise addition, the mixture was stirred at room temperature for about 30 minutes. Then, the formed precipitate was collected by filtration and washed with water. It was dried to obtain 31.7 g (yield: 74%) of the desired product. Melting point: 162-163 C.
The synthetic route of 6306-60-1 has been constantly updated, and we look forward to future research findings.
