Abstract

The title compound, C₂₁H₂₁N₃O₂, was obtained following a five-step synthetic procedure yielding weakly diffracting rod and needle-shaped crystals which crystallized concomitantly. Structural analysis of a rod-shaped crystal showed that the central seven-membered heterocyclic ring adopts a conformation that is perhaps best described as a distorted boat, with the H-bearing (CH₂ and NH) atoms lying well out of the least-squares mean plane fitted through the other five atoms in the ring (r.m.s. deviation 0.075 Å). In the crystal, the compound packs as a twisted chain, which propagates along the b axis by means of an R ¹₂(6) motif formed by one of the carbonyl O atoms acting as a bifurcated acceptor in an N - H⋯O and C - H⋯O inter-action. No diffraction was observed from the needle-shaped crystals.
