In the title compound, C 12 H 11 N 3 OS, the interplanar angle between the pyrazole and benzothiazole rings is 3. 31 (7) °. In the three-dimensional molecular packing, the carbonyl oxygen acts as acceptor to four C—H donors (with one H. . . O as short as 2. 25 Å), while one methyl hydrogen is part of the three-centre system H. . . (S, O). A double layer structure parallel to (101) can be recognized as a subsection of the packing.
