Source of material

The title compound was synthesized according to a reported procedure [5]. Single crystals suitable for X-ray diffraction were obtained by slow evaporation from ethyl acetate at room temperature.

Experimental details

All H atoms were positioned geometrically and constrained to ride on the parent atoms, N—H = 0.86 Å, C—H = 0.93–0.98 Å with Uiso(H) = 1.5Ueq(methyl C) or 1.2Ueq(C, N) for other H atoms.

Discussion

The title compound is an important intermediate of the Lacosamide synthesis. Lacosamide (trade name Vimpat) is an anticonvulsant drug approved for the adjunctive treatment of partial-onset seizures and neuropathic pain [6], [7]. Lacosamide has a dual mechanism underlying its anticonvulsant and analgesic activity. It selectively enhances slow inactivation of voltage-gated sodium channels and regulates the collapse response mediator protein 2 (CRMP2) [8], [9].

The asymmetric unit of the title compound contains one single target molecule. The torsion angle of C9–C10–O2–C10 is −71.0(3)°. There are several weaker intramolecular C—H⋯O non-classical hydrogen bonds in the crystal structure. The components are linked by weak classical intermolecular N—H⋯O hydrogen bonds to form chains propagating along [010]. These hydrogen bonds contribute to the stabilization of the crystal packing.
