چکیده
The asymmetric unit of the title compound, C(12)H(13)NO(3), contains two independent mol-ecules. The conformation of the N-H bond and the C=O bond in the amide segment are anti to each other. The mol-ecular conformation of each mol-ecule is stabilized by an intra-molecular O-H⋯O hydrogen bond. In the crystal, mol-ecules are connected through intermolecular N-H⋯O hydrogen bonds. In addition, there is a carbon-yl-carbonyl dipolar inter-action with an O⋯C contact of 2.926 (3) Å.

The title compound, 2C(17)H(20)N(2)O·CH(2)Cl(2), was obtained by N-oxidation of the parent formamidine with m-chloro-peroxy-benzoic acid (m-CPBA). This is the first use of the above-mentioned synthetic route for the preparation of hydroxy-amidines. The title compound crystallizes as a cyclic dimer resulting from the presence of O-H⋯O and N-H⋯N hydrogen bonds.
