Pivaloylacetonitrile Use and Manufacturing

Methods of Manufacturing

NaH (50 percent in paraffin oil) (1.2 eq., 4.6 g) was dissolved in 1 , 4-dioxane (120 ml) and the mixture was stirred for a few minutes. Acetonitrile (1.2 eq., 4.2 g) was added dropwise within 15 min and the mixture was stirred for a further 30 min. The methyl pivalate (J-I) (1 eq., 10 g) was added dropwise within 15 min and the reaction mixture was refluxed for 3 h. After complete reaction, the reaction mixture was placed in iced water (200 g), acidified to pH 4.5 and extracted with dichloromethane (12 x 250 ml). The combined organic phases were dried over sodium sulphate, distilled and after recrystallisation from hexane (100 ml) 5 g of the product (J-Il) (51 percent yield) was able to be obtained as a solid brown substance.NaH (50 percent in paraffin oil) (1.2 eq., 4.6 g) was dissolved in 1 , 4-dioxane (120 ml) and the mixture was stirred for a few minutes.
