Abstract
In the title compound, C15H12N2S, the methylthioquinazoline group is planar with the methyl C displaced by only 0.116 (3) angstrom from the plane of the quinazoline moiety. The dihedral angle between the phenyl ring and the quinazoline ring system is 13.95 (5)degrees. In the crystal, each molecule is linked by pi-pi stacking between to two adjacent inversion-related molecules. On one side, the inverted quinazoline groups interact with a centroid-centroid distance of 3.7105 (9) angstrom. On the other side, the quinazoline group interacts with the pyrimidine and phenyl rings of the second neighbour with centroid-centroid distances of 3.5287 (8) and 3.8601 (9) angstrom, respectively.
