The title compound, C21H21N5O2, is a 1,4-dimethyl-1,2,3-triazole having dimethylbenzodiazepindione and phenyl substituents on each methyl group; the substituents are positioned on opposite sides of the five-membered ring. The seven-membered fused-ring of the larger substituent adopts a boat-shaped conformation (with the methine C atom as the prow).

To a solution of 1,5-dimethyl-3-propargyl-1,5-benzodiazepine-2,4-dione (1 mmol) in t-butyl alcohol/water (1/2, 8 ml) was added copper sulfate pentahydrate (1 mmol), sodium ascorbate (2 mmol) and benzyl azide (5 mmol). The mixture was stirred for 8 h. The solution was then diluted with water (20 ml) and the organic compound extracted with ethyl acetate (2 × 20 ml). The extracts were washed with brine and dried over sodium sulfate. The compound was recrystallized from ether to give colorless crystals.
Carbon-bound H atoms were placed in calculated positions (C—H 0.93–0.98 Å) and were included in the
in the riding model approximation, with U(H) set to 1.2–1.5U(C).Data collection: APEX2 (Bruker, 2005); cell
