In the crystal structure of the title compound, C 16 H 17 N 5 O 2 S, molecules are linked by two N-HÁ Á ÁS hydrogen bonds, with N-S distances of 3.3469 (13) and 3.3703 (13) A ˚and N-H Á Á ÁS angles of 158 and 162 .
In the title compound, C 15 H 18 N 2 O 4 S, the packing is consolidated by an intra/intermolecular bifurcated O-HÁ Á Á(O,O) and intermolecular N-HÁ Á ÁS hydrogen bonds. The tetrahydropyrimidin-2-one ring is twisted. ## Related literature For background, see: Kappe (1993). ## Experimental Cryst
