(Received 9 September 2008; accepted 10 September 2008; online 13 September 2008)

The title compound, C₂₂H₂₆N₂O₃, was synthesized by esterification of trans-rac-2-hexyl-1-oxo-3-(2-pyridyl)-1,2,3,4-tetrahydroisoquinoline-4-carboxylic acid in the presence of H₂SO₄ in methanol. The dihedral angle between the benzene and pyridine rings is 84.46 (17)°. The piperidine ring adopts a screw-boat conformation. In the crystal, inversion dimers linked by two C—H⋯O bonds occur.

Comment top

The title compound was synthesized as part of a research project to find precursors for the production of new tetrahydroquinolone derivatives with potential biological activity (Kandinska et al., 2006; Kandinska et al., 2007).

The molecular structure is shown in Fig.1. The bond lengths and angles are in normal ranges (Allen et al., 1987). The dihedral angle between the benzene and pyridine rings is 84.46 (17) °. The piperidine ring adopts a screw boat conformation and its puckering parameters (Cremer & Pople, 1975) are Q_T = 0.465 (3) Å, θ = 114.9 (4)° and ϕ = 93.7 (4) °.

The crystal structure is stabilized by intermolecular C—H···O hydrogen bonds (Table 1 and Fig. 2).

Experimental top

The title compound was synthesized by esterification of trans-rac-2-hexyl-1-oxo-3-(pyridin-2-yl)-1,2,3,4-tetrahydroisoquinoline-4-carboxylic acid (3.81 g, 0.011 mol) (Kandinska et al., 2007) in the presence of H₂SO₄ (1.7 ml, 0.032 mol) in methanol. After working up the reaction mixture, the title compound crystallized as white crystals from ethyl acetate (yield 3.56 g, 90%; m.p. 357–359 K). Analysis, calculated for C₂₂H₂₆N₂O₃ (366.45): C 72.11, H 7.15%; found: C 72.35, H7.08%. The product was further characterized by ¹H NMR and IR spectra.

Special details top

Experimental. Single crystals were obtained by slow evaporation of a solution of the title compound in ethyl acetate at room temperature. IR (CHCl₃) 1600 cm^-1 (ArH), 1660 cm^-1 (C=O), 1740 cm^-1 (C=O). ¹HNMR (250 MHz, CDCl₃) δ (p.p.m.) = 0.83–0.86 (m, 3H, -CH₃), 1.18–1.35 (m, 6H, -CH₂-), 1.58–1.67 (m,2H, -CH₂-), 2.81–2.88 (m,1H, N—CH₂^a), 3.70 (s, 3H, -OCH₃), 4.20–4.28 (m, 1H, N—CH₂^b), 4.42 (s, 1H, -OOC-CH), 5.32 (s, 1H, Pyr-CH, 6.90–6.98 (m, 1H, Ph-H), 7.08–7.19 (m, 2H, Ph-H, Pyr-H), 7.25–7.30 (m, 2H, Pyr-H), 7.36–7.47 (m, 1H, Ph-H), 7.87 (dd, 1H, J = 2.0 and 10.0 Hz, Ph-H),8.08 (dm, 1H,J = 4.0 Hz, Pyr-H).

Geometry. Bond distances, angles etc. have been calculated using the rounded fractional coordinates. All su's are estimated from the variances of the (full) variance-covariance matrix. The cell e.s.d.'s are taken into account in the estimation of distances, angles and torsion angles

Refinement. Refinement on F² for ALL reflections except those flagged by the user for potential systematic errors. Weighted R-factors wR and all goodnesses of fit S are based on F², conventional R-factors R are based on F, with F set to zero for negative F². The observed criterion of F² > σ(F²) is used only for calculating -R-factor-obs etc. and is not relevant to the choice of reflections for refinement. R-factors based on F² are statistically about twice as large as those based on F, and R-factors based on ALL data will be even larger.
