【 摘 要 】

In the title solvated compound, C24H17N5O4·C2H6OS, the solvent molecule, dimethyl sulfoxide, is linked to the title molecule by an N—H...O hydrogen bond. The pyridine ring adopts a twist-boat conformation. The isoxazole ring is inclined to the indoline ring system, the pyrimidine ring, and the phenyl ring by 82.31 (7), 10.41 (8) and 53.77 (10)°, respectively. There is an intramolecular C—H...π interaction present involving the phenyl ring and the indoline ring system. In the crystal, molecules are connected by two pairs of N—H...O hydrogen bonds, forming chains along the b-axis direction, and enclosing R22(8) and R22(14) ring motifs. The chains are linked by C—H...O and C—H...N hydrogen bonds and offset π–π interactions, between the pyrimidine and isoxazole rings of inversion-related molecules [centroid–centroid distance = 3.7140 (9) Å], forming a three-dimensional structure.
