## Abstract An efficient synthesis of 3‐alkyl‐3,4‐dihydro‐4‐thioxobenzoquinazolin‐2(1__H__)‐ones **3** has been accomplished in two steps and in satisfactory yields from 1‐bromo‐2‐fluorobenzenes **1**. Thus, the reaction of 1‐fluoro‐2‐lithiobenzenes, generated by the Br/Li exchange between **1** an
