| titleOfInvention | A kind of synthetic method of 9- ethyl adenines |
| abstract | The present invention relates to the synthesis technical field of chemical organic substance more particularly to a kind of synthetic methods of 9 ethyl adenine.Its step is：A, adenine, potassium carbonate, bromoethane are added to n,N-Dimethylformamide, heating reaction is centrifuged off potassium carbonate, and filtrate is dense dry；B, in the product of step A plus acetone heat dissolved clarification, cool down, crystallization, filter 9 ethyl adenines crude product filter cake；C, by the crude product filter cake of 9 ethyl adenines of step B add acetone heat dissolved clarification, cool down, crystallization, filter 9 ethyl adenine fine work filter cakes, fine work filtration cakes torrefaction obtain 9 ethyl adenine of product.So that first step reaction, which generates the 9 fast purity of ethyl gland, reaches 85% or more.Pass through rear two one-step refining so that product purity reaches 99.5% or more.The present invention reaction step it is simple, operating condition is mild, it is easy to control, reaction also without by-product, the feature of environmental protection is good. |
