## Abstract The reaction of 3‐__N__‐(2‐mercapto‐4‐oxo‐4__H__‐quinazolin‐3‐yl)acetamide (**1**) with hydrazine hydrate yielded 3‐amino‐2‐methyl‐3__H__‐[1,2,4]triazolo[5,1‐__b__]quinazolin‐9‐one (**2**). The reaction of **2** with __o__‐chlorobenzaldehyde and 2‐hydroxy‐naphthaldehyde gave the corresp
In the title compound, C 18 H 15 N 3 OS, the three fused rings of the benzothienopyrimidinone are essentially coplanar. The crystal structure is stabilized by C-HÁ Á ÁO and C-HÁ Á ÁS hydrogen bonds.
