Source of material
n-Dipropylamine (2.3 g, 0.023 mol) was added to a solution of 1-(chloroacetyl)-2,3-diphenyl-1,3-diazaspiro[4.5]decan-4-one (1.8 g, 0.0047 mol) in toluene (40 mL) and the reaction mixture was heated at 90 °C for 20 h. After cooling to room temperature the solvent was removed under reduced pressure to give a residual oil which was dissolved in dichloromethane (100 mL). The organic phase was washed with water, dried (Na2SO4) and evaporated under vacuum to yield the title compound as a viscous oil. The crude oil was purified by column chromatography using silica gel as a stationary phase and a mixture of petroleum ether (40–60 °C): ethyl acetate (7:3) as a mobile phase to give the title compound as a white solid; m.p. 411–413 K in 65% yield [4]. The title compound was re-crystallized from ethyl acetate to afford colorless single crystals.
Experimental details
Carbon-bound hydrogen atoms were placed in calculated positions and were included in the refinement using the riding model approximation, with Uiso(H) set to 1.2Ueq(C) and 1.5Ueq(Methyl).
Discussion
Epilepsy is a chronic disorder of the brain that affects approximately 50 million people, making it one of the most common neurological diseases worldwide [5]. Many new antiepileptic drugs have been introduced in the market, however the available antiepileptics fail to prevent the seizures in approximately 30% of patients [6]. Moreover, these medications are associated with severe adverse effects such as gingival hyperplasia, megaloblastic anaemia and hepatotoxicity [7, 8] . Therefore, there is a great need for the development of new, more effective and less toxic antiepileptic agents. The title compound displayed 83% protection toward subcutaneous pentylenetetrazole -induced convulsions in mice at dose level 0.035 mmol/kg [3].
In the crystal structure of the title compound, the asymmetric unit contains one independent molecule. Molecules form extended chains along the crystallographic c direction via one non-classical intermolecular hydrogen bond, C1—H1A ⋯O1i, symmetry code: (i) x, − y + 1/2, z-1/2, with a D ⋯A distance of 3.300 Å and a D—H ⋯A angle of 175°.
