In the title compound, C20H22N6, the molecules are linked into a chain of rings by N-H...N [H...N 2.16 A, N...N 2.950 (3) A and N-H...N 149°] and C-H...N [H...N 2.55 A, C...N 3.481 (3) A and C-H...N 165°] hydrogen bonds, and these chains are linked into sheets by means of C-H...π(pyrazole) interactions.

A rearrangement product or a pyrazolic Tr?ger's base were unexpectedly obtained when 5-N-(benzotriazol-1-ylmethyl)amino-3-tert-butyl-1-phenylpyrazole was treated with electron-rich alkenes with well protic or Lewis acid catalyst, respectively, when tetrahydropyrazolopyridines were expected according with the benzotriazole methodology. The structure of the products was confirmed by NMR and X-ray diffraction techniques. Mechanisms for their formation are also proposed.
