Synthetic Route of 630-18-2, As we all know, there are many different methods for the synthesis of a compound, and people can choose the synthesis method that suits their own laboratory according to the actual situation. 630-18-2 name is Pivalonitrile, This compound is widely used in many fields, so it is necessary to find a new synthetic route. The downstream synthesis method of this compound is introduced below.
General procedure: To an ice cold solution of pivalonitrile (1f, 120 muL, 1.085 mmol) in Et2O (1.0 mL)was added an ethereal solution of 2-naphthylmagnesium bromide (2b, 0.75 M, 1.88mL, 1.410 mmol) and the reaction mixture was stirred at 60 C in a sealed tube for 2 h.After cooling to 0 C, the reaction mixture was treated with anhydrous MeOH (132muL), followed by the addition of CuBr2 (24.3 mg, 0.109 mmol) and anhydrous DMF(10.0 mL). The resulting reaction mixture was stirred at 80 C under an oxygenatmosphere for 6 h. Then the reaction was quenched by the addition of pH 9ammonium buffer solution and the organic materials were extracted with Et2O. Thecombined organic extracts were washed with water, and then with brine and driedover anhydrous MgSO4. The solvents were removed in vacuo and the resulting crudematerial was purified by flash column chromatography using hexane-EtOAc (90:10)to afford 2-naphthonitrile
At the same time, in my other blogs, there are other synthetic methods of this type of compound, Pivalonitrile, and friends who are interested can also refer to it.
