4-[(2,5-Dimethyl-1,3-thiazol-4-yl)methyl]-4-hydroxy-2-methylisoquinoline-1,3(2H,4H)-dione

In the title isoquinolinedione compound, C16H16N2O3S, the piperidine ring in the tetrahydroisoquinoline ring system adopts a half-boat conformation. The essentially planar thiazole ring [maximum deviation = 0.007 (2) Å] makes a dihedral angle of 34.49 (7)° with the mean plane through the tetrahydroisoquinoline ring system. In the crystal structure, two neighbouring molecules are linked via pairs of O—H...N and C—H...O hydrogen bonds into inversion-related dimers incorporating R22(9) hydrogen-bond ring motifs. These dimers are further linked by weak intermolecular C—H...π interactions.
