Abstract
In the title compound, C11H11N3O, the aromatic rings at either ends of the –CH2–NH– link are twisted by 72.58 (8)°; the hydroxy substituent is a hydrogen-bond donor to an N atom of the pyrimidine ring. The other N atom of the pyrimidine ring is a hydrogen-bond acceptor to the amino group of an inversion-related molecule.

Comment
There are numerous studies on the Schiff bases derived by condensing salicyldehyde and an aromatic amine. In this study, the azomethine double-bond of N-salicylidene-2-aminopyrimidine (El-Haty et al., 1990; Issa et al., 2011; Shalabi & Abdel-Ghani, 1990) is reduced by sodium borohydride to yield the title secondary amine (Scheme I). The two aromatic rings at either ends of the –CH2–NH– link of C11H11N3O are twisted by 72.58 (8)°; the hydroxy substituent is hydrogen-bond donor to anone N atom of the pyrimidyl ring (Fig. 1). The other N atom of the pyrimidyl ring is hydrogen-bond acceptor to the amino group of an inversion-related molecule (Table 1).
Experimental
A solution of 2-aminopyrimidine (1 mmol) and salicylaldehyde (1 mmol) in toluene (50 ml) was heated for 10 h. The solvent was removed under vacuum, and the residue was reduced in absolute methanol by sodium borohydride. Colorless crystals were obtained by recrystallization from methanol; yield 80%.
Refinement
Carbon-bound H-atoms were placed in calculated positions (C–H 0.93–0.97 Å) and were included in the refinement in the riding model approximation, with Uiso(H) = 1.2Ueq(C). The amino and hydroxy H-atoms were located in a difference Fourier map, and were refined with distance restraints N–H 0.88±0.01 Å and O–H 0.84±0.01 Å; their temperature factors were refined.
