Ethyl 2-(1H-1,2,3-benzotriazol-1-yl)acetate.

The title compound, C(10)H(11)N(3)O(2), was synthesized by the reaction of 1H-benzotriazole with ethyl 2-chloro-acetate in ethanol. The non-H atoms, excluding the benzotriazol-1-yl group, are almost coplanar (r.m.s. deviation of the non-H atoms = 0.0409 Å). The dihedral angle formed between this plane and the benzotriazole ring is 79.12 (5)° In the crystal, weak inter-molecular C-H⋯N and C-H⋯O inter-actions help to consolidate the three-dimensional network
