Some common heterocyclic compound, 33143-29-2, name is 2,2-Dimethyl-2H-chromene-6-carbonitrile, molecular formula is C12H11NO, 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. Formula: C12H11NO
A solution of 2,2-dimethyl-2H-chromene-6-carbonitrile (300 mg, 1.62 mmol) in diethyl ether (2 ml) was added dropwise to a suspension of lithium aluminum hydride (135 mg, 3.56 mmol) in diethyl ether (3 ml) at 0 C. After 30 minutes of stirring at 0 C the mixture was brought to room temperature. After 1 hour of stirring at room temperature, sodium sulfate decahydrate was added in small portions until gas evolution ceased. The mixture was filtered and the organic solution was concentrated to oil (269 mg, 88 %).
These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route 33143-29-2, its application will become more common.
