- A new method for synthesizing zaleplon (by machine translation)
-
The present invention provides a new method for synthesizing zaleplon. In particular, the method of the invention takes the acetophenone as raw materials, make N-ethyl-N-[ 3 - (3- dimethyl amine -1-oxo-2-propenyl) phenyl] acetamide, with 3-amino-4-cyano pyrazole reaction, forming N-[ 3 - (3-cyano-pyrazolo [1,5-α] pyrimidin-7-yl) phenyl]-N-ethyl acetamide. The synthetic route of the present invention of fewer steps, after treatment is simple, low cost, suitable for industrial production. (by machine translation)
