tert-Butyl N-{4-methyl-3-[4-(3-pyrid-yl)pyrimidin-2-yl-oxy]phen-yl}carbamate.

In the mol-ecule of the title compound, C(21)H(22)N(4)O(3), the pyrimidine ring is oriented at dihedral angles of 0.51 (3) and 50.76 (3)° to the pyridine and benzene rings, respectively. In the crystal structure, inter-molecular N-H⋯N hydrogen bonds link the mol-ecules into centrosymmetric dimers, forming R(2) (2)(24) ring motifs; the dimers are linked by inter-molecular C-H⋯O hydrogen bonds into a two-dimensional network. π-π contacts between the benzene rings and between the pyrimidine and pyridine rings [centroid-centroid distances = 3.891 (1) and 3.646 (1) Å, respectively] may further stabilize the structure. Two weak C-H⋯π inter-actions are also present.
