© 2022 Khrustalev et al.In the title compound, C21H22N2O3S, the 1,2-oxazole ring makes the dihedral angles of 9.16 (16) and 87.91 (17)°, respectively, with the toluene and phenyl rings, while they form a dihedral angle of 84.42 (15)° with each other. The C - S - N - Cpr and C - S - N - Cme (pr = propene, me = 3-methyl-1,2-oxazole) torsion angles are 86.8 (2) and -100.6 (3) °, respectively. In the crystal, molecules are linked by C - HO hydrogen bonds, generating a three-dimensional network. A Hirshfeld surface analysis was performed to investigate the contributions of the different intermolecular contacts within the supramolecular structure. The major interactions are HH (53.6%), CH/HC (20.8%) and OH/HO (17.7%).
