4-(3,5-Dimethoxyphenyl)-6-(2-methoxyphenyl)pyrimidin-2-amine

Abstract

In the title molecule, C19H19N3O3, the 2-methoxyphenyl and 3,5-dimethoxyphenyl rings are attached at the 4- and 6-positions, respectively, of the central 2-aminopyrimidine ring. The dihedral angles between the planes of the benzene rings and that of the 2-aminopyrimidine ring are 17.31 (9) and 44.39 (6)°, respectively. In the crystal, pairs of N—H...N hydrogen bonds form inversion dimers enclosing R22(8) rings. Pairs of N—H...O hydrogen bonds link the dimers into chains along [010].
