Abstract

The title compound, C₂₃H₂₅N₃O₂, was obtained as an intermediary in the preparation of non-symmetric tertiary diamines. The molecular structure presents T-shaped spatial form, in which the pyrimidine ring exhibits a chair conformation. The pyridyl ring is almost perpendicular to the phenyl rings with dihedral angles of 80.17 (8) and 76.03 (2)°. The phenol and amine groups are involved in two strong intramolecular O—H⋯N interactions. In the crystal, the molecules are stacked along [010]; however, no intermolecular interactions are observed.

Comment

The molecular structure of the title compound (I) shows T-shaped spatial form (Fig. 1). Pyrimidine ring adopts regular chair conformation with square plane formed by N1/C2/C4/C5 atoms (r.m.s. deviation = 0.0111).

The dihedral angles between the mean planes of the rings C31/C36 and C11/C16 of 80.17 (8)° and C31/36 and C211/C26 of 76.03 (8)° demonstrate that pyridil ring is almost perpendicular to phenol groups.

Two strong intramolecular O—H···N hydrogen bonds between phenol and amine groups (Table 1) form additional six-membered rings, which contribute for the rigidity of the structure and avoid the crystal supramolecurity.

The molecules are stacked along [010] direction, however no further intermolecular interactions, such as π-stacking, were observed.

All bond lengths and angles found for (I) are in the expected range for organic compounds (Bruno et al., 2004).

Experimental

Compound (I) was synthesized according to the procedure described by Hureau et al. (2008).

A solution containing 6.0 g of N,N'-bis(2-hydroxybenzyl)-1,3-diamino-propane (21,3 mmol) and 2.39 g (21,3 mmol) of 2-pyridinecarboxaldehyde in 60 ml of MeOH was stirred at temperature of 333,15 K for 1 h. The solvent was evaporated under reduced pressure to afford a white precipitate, which was filtered off and washed with dry diethyl eter. (85% yield = 85%). MP 154.6–154.9 °C, EA for C₂₃H₂₅N₃O₂: calc C 73,53%; H 7,18%; N 11,27%, found C, 73.57%; H, 6.71%; N, 11.195.
