실험 절차

0.950 g (2.59 mmol) of 4-chloro-2-[4-(4-chlorophenyl)piperazin-1-yl]-6,7-dihydrothieno[3,2-d]pyrimidine (III) is placed in 20 mL of dimethylformamide and 0.900 g (13.84 mmol) of sodium azide is added. The reaction mixture is stirred for 4 hours at 100° C. It is then concentrated by evaporation, the residue is cooled in the ice bath and combined with water. The precipitate formed is suction filtered, washed, and dried. 0.920 g of product IV (76%) is obtained and used further in the crude state.
