(Received 15 October 2008; accepted 10 November 2008; online 13 November 2008)

The title compound, C13H13N2O+·Cl−, (1), was obtained as a colorless crystalline by-product during the synthesis of N-(2-pyridylmeth­yl)benzoyl­amine (2). The C—O bond length of 1.231 (2) Å in the benzoyl unit of (1) is slightly elongated in comparison with isolated C=O double bonds as also observed for (2) [1.237 (2) Å]. The N—C bond length of 1.345 (2) Å in the benzoic acid amide unit indicates the formation of an allylic O—C—N system and is very similar to the N—C bond lengths [1.345 (2) Å] of the pyridyl group. A further delocalization of charge from this allylic system into the phenyl fragment does not occur, which can be deduced from a characterisitc C—C single bond length of 1.499 (2) Å between these fragments. A dimer is formed via N—H⋯Cl hydrogen bonds. The two rings make a dihedral angle of 105.0 (2)°

Comment top

In the past, metallated (2-pyridylmethyl)(trialkysilyl)amines were used for zinc-mediated oxidative C–C coupling reactions yielding [1,2-dipyridyl-1,2-bis(triisopropylsilylamido)ethane] bis(methylzinc) (Westerhausen et al. 2001 and 2002). The reaction of (2-pyridylmethyl)(tert-butyldimethylsilyl)amine and benzoyl chloride in toluene quantitatively yields N-(2-pyridylmethyl)benzoylamine ((1)) (Koch et al. 2008). Treatment of (1) with benzoyl chloride after deprotonation with butyllithium gives N-(2-pyridylmethyl)dibenzoylamine with rather poor yields. The title compound N-(2-pyridylmethyl)benzoylamine hydrochloride was also obtained as a colorless crystalline by-product.

A view of the title compound is shown in Fig. 1 . The C1—O1 bond length of 1.231 (2) Å is slightly elongated in comparison to isolated C=O double bonds. The value of the N1—C1 bond length of 1.345 (2)Å shows the formation of an allylic O1—C1—N1 system and is very similar to the N2—C9 bond length [1.345 (2) Å] of the pyridyl group. A further delocalization of charge from this allylic system into the phenyl fragment can be excluded on the basis of a characterisitc C8—C9 single bond of 1.499 (2) Å.

Two molecules are linked through N-H···Cl hydrogen bonds to form a pseudo dimer (Table 1, Fig. 2)

Experimental top

All manipulations were carried out in an atmosphere of argon using standard Schlenk techniques. Toluene and pentane were dried (Na/benzophenone) and distilled prior to use. 2-Pyridylmethylamine and butyllithium were purchased form Aldrich. Tert-butyldimethylchlorosilane and benzoyl chloride were purchased from Merck.1H NMR and 13C NMR spectra were recorded at [D1]chloroform solutions at ambient temperature on a Bruker AC 400 MHz s pectrometer and were referenced to deuterated benzene as an internal standard. 1H NMR (200 MHz, [D1]chloroform) d = 8.93 (s, br.,1H, NH); 8.63 (d, 1H, Pyr13); 8.35 (t, 1H, Pyr11); 8.06 (d, 1H, Pyr10); 7.98 (d, 2H, Ph); 7.79 (t, 1H, Pyr12); 7.48–7.37 (m, 3H, Ph); 5.03 (d, 2H, CH2)

Special details top

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes.

Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > σ(F2) is used only for calculating R-factors(gt) 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.
