Abstract

Pyrazole derivatives R 0180 4-Functionally Substituted 3-Heterylpyrazoles. Part 14. N-Benzyl-N-[3-aryl(heteryl)-4-pyrazolylmethylene]amines and Their Derivatives. -The title compounds (II) are obtained in good yields by reduction of the corresponding Schiff bases (I) with NaBH4. The reactions of the amines (II) with Ph-NCS, Bz-Cl, and anhydrides are used for the preparation of their N-substituted derivatives (IV), (VI), (VIII), and (X). -(BRATENKO, M. K.; PANIMARCHUK, O.
