The molecules of 3‐ tert ‐butyl‐5‐[(4‐methoxybenzyl)amino]‐1‐phenyl‐1 H ‐pyrazole, C 21 H 25 N 3 O, are linked into simple C (9) chains by a single C—H⋯N hydrogen bond. 5‐[(Benzotriazol‐1‐ylmethyl)(4‐methoxybenzyl)amino]‐3‐ tert ‐butyl‐1‐phenyl‐1 H ‐pyrazole, C 28 H 30 N 6 O, crystallizes with Z ′ = 2 in the space group P 2 1 / c . The molecules are weakly linked into centrosymmetric tetramolecular aggregates by a combination of C—H⋯N and C—H⋯O hydrogen bonds.
