In the title compound, C14H10N2O2S, the benzothiazole and quinazoline ring systems are essentially planar with maximum deviations of 0.0127 (16) and 0.1588 (15) Å, respectively, and make a dihedral angleof 3.02 (5)°, which shows that the entire molecule is almost planar. The O atoms deviate from the benzothiazole ring system by 1.2231 (14) and -1.1989 (15) Å. The crystal packing features non-classical C-HO hydrogen bonds and is further consolidated by - interactions [centroid-centroid distances = 3.7568 (8) and 3.8848 (9) Å].
