    摘要: A process for purifying Anastrozole is provided. In the process the steps of
    a. extracting a quenched reaction mixture containing anastrazole with a mixture of toluene, linear, branched or cyclic C 5-8 hydrocarbon and water;
    b. extracting the aqueous phase using a mixture comprising of toluene and linear, branched or cyclic C 5-8 hydrocarbon;
    c. adding water;
    d. extracting the aqueous phase using toluene;
    e. washing the organic phase with an aqueous solution of an acid;
    f. adding linear, branched, or cyclic C 5-8 hydrocarbon to the organic phase to precipitate Anastrozole,

    are performed.
