Application of 98730-77-9,Some common heterocyclic compound, 98730-77-9, name is 1-(Hydroxymethyl)cyclopropanecarbonitrile, molecular formula is C5H7NO, 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.
Thionyl chloride (1.6 mL) was added to a solution of 1-(hydroxymethyl)cyclopropanecarbonitrile (1.42 g) in toluene (20 mL) at room temperature. The reaction mixture was stirred at 80C for 2 hr, and the solvent was evaporated. The resulting residue was dissolved in DMF (20 mL), and 2-bromo-5-(4-hydroxy-3-methoxyphenyl)furo[3,2-c]pyridin-4(5H)-one (2.45 g) and potassium carbonate (4.03 g) were added. The mixture was stirred at 80C overnight. To the reaction mixture was added saturated aqueous ammonium chloride solution, and the mixture was extracted with ethyl acetate three times. The resulting organic layer was dried over magnesium sulfate and concentrated in vacuo, and the resulting residue was filtered through NH silica gel. The filtrate was concentrated in vacuo, and the resulting solid was washed with IPE to give the title compound (2.80 g) as a white solid. MS (ESI+):[M+H]+ 416.1.
These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route 1-(Hydroxymethyl)cyclopropanecarbonitrile, its application will become more common.
