Synthetic Route of 6318-51-0, 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. 6318-51-0, name is (4-Chlorophenyl)(pyridin-2-yl)methanone, molecular formula is C12H8ClNO, The 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.
In a 5L autoclave, under the condition of argon, 400 g of (4-chlorophenyl)(pyridin-2-yl)methanone was added from the feed inlet; 3 L of toluene was added; Bubble out of gas, continuous bubbling 30min; degassing is complete. Under an argon atmosphere, 100 mg of catalyst (R,R)-DIOPRuCl2(R)-Me-BIMAH was added from the feed port, and finally 6 g of potassium tert-butoxide was added; after the addition was completed, the feed port was quickly closed tightly. Replacing argon with hydrogen gas and slowly introducing hydrogen gas to 35 atm, and then closing the inflation valve and closing the hydrogen channel; finally stirring, maintaining the reaction at 35 C.; after the start of stirring, the pressure dropped. Observe the changes in pressure, after 4h, the pressure no longer changes, sampling for GC analysis,The conversion rate was 99.7% and the ee value was 98.2%.
According to the analysis of related databases, 6318-51-0, the application of this compound in the production field has become more and more popular.
